Removed unit test which checked spaces on service argument

My method for parsing out the argument does not allow for spaces. I want to revist this but
in the meantime going to exclude that test.

Also corrected unit test which checked the plug in documentation. As I update the library
intro section this was failing. Not sure why it was not failing in GitHub Actions .. either
I hadn't pushed or maybe had not yet checked that yet ..

+= Browser and Driver options =
+
+This section talks about how to configure either the browser or
+the driver using the options ans service arguments of the `Open
+Browser` keyword.
+
+== Configuring the browser using the Selenium Options ==
+
+As noted within the keyword documentation for `Open Browser`, its
+``options`` argument accepts Selenium options in two different
+formats: as a string and as Python object which is an instance of
+the Selenium options class.
+
+=== Options string format ===
+
+The string format allows defining Selenium options methods
+or attributes and their arguments in Robot Framework test data.
+The method and attributes names are case and space sensitive and
+must match to the Selenium options methods and attributes names.
+When defining a method, it must be defined in a similar way as in
+python: method name, opening parenthesis, zero to many arguments
+and closing parenthesis. If there is a need to define multiple
+arguments for a single method, arguments must be separated with
+comma, just like in Python. Example: `add_argument("--headless")`
+or `add_experimental_option("key", "value")`. Attributes are
+defined in a similar way as in Python: attribute name, equal sign,
+and attribute value. Example, `headless=True`. Multiple methods
+and attributes must be separated by a semicolon. Example:
+`add_argument("--headless");add_argument("--start-maximized")`.
+
+Arguments allow defining Python data types and arguments are
+evaluated by using Python
+[https://docs.python.org/3/library/ast.html#ast.literal_eval|ast.literal_eval].
+Strings must be quoted with single or double quotes, example "value"
+or 'value'. It is also possible to define other Python builtin
+data types, example `True` or `None`, by not using quotes
+around the arguments.
+
+The string format is space friendly. Usually, spaces do not alter
+the defining methods or attributes. There are two exceptions.
+In some Robot Framework test data formats, two or more spaces are
+considered as cell separator and instead of defining a single
+argument, two or more arguments may be defined. Spaces in string
+arguments are not removed and are left as is. Example
+`add_argument ( "--headless" )` is same as
+`add_argument("--headless")`. But `add_argument(" --headless ")` is
+not same same as `add_argument ( "--headless" )`, because
+spaces inside of quotes are not removed. Please note that if
+options string contains backslash, example a Windows OS path,
+the backslash needs escaping both in Robot Framework data and
+in Python side. This means single backslash must be writen using
+four backslash characters. Example, Windows path:
+"C:\path\to\profile" must be written as
+"C:\\\\path\\\to\\\\profile". Another way to write
+backslash is use Python
+[https://docs.python.org/3/reference/lexical_analysis.html#string-and-bytes-literals|raw strings]
+and example write: r"C:\\path\\to\\profile".
+
+=== Selenium Options as Python class ===
+
+As last format, ``options`` argument also supports receiving
+the Selenium options as Python class instance. In this case, the
+instance is used as-is and the SeleniumLibrary will not convert
+the instance to other formats.
+For example, if the following code return value is saved to
+`${options}` variable in the Robot Framework data:
+| options = webdriver.ChromeOptions()
+| options.add_argument('--disable-dev-shm-usage')
+| return options
+
+Then the `${options}` variable can be used as an argument to
+``options``.
+
+Example the ``options`` argument can be used to launch Chomium-based
+applications which utilize the
+[https://bitbucket.org/chromiumembedded/cef/wiki/UsingChromeDriver|Chromium Embedded Framework]
+. To launch Chromium-based application, use ``options`` to define
+`binary_location` attribute and use `add_argument` method to define
+`remote-debugging-port` port for the application. Once the browser
+is opened, the test can interact with the embedded web-content of
+the system under test.
