Fix incorrect case/capitalization in ref docs

This ensures the following components have the correct/consistent case
throughout the reference documentation:

Preference variable, PS environment variable, PS drive, PS provider,
PS command name, PS command argument, PS module, PS file extension,
PS host name/application, #Requires statement, parameter name,
about_* topic, member name, scope modifier, keyword, operator,
calculated property key/value, attribute, type accelerator,
type literal/name, WMI namespace/class, variable name,
special character, comment-based help keyword, product/company name,
Windows drive letter/directory, Windows/Unix environment variable

In addition, changes include fixes to incorrect terminology (e.g.,
referring to a keyword as a command) and formatting of PS syntax
elements (non-exhaustive).
