errors: use non-hyphen anchor for NoSuchElementException

[HaniASU]

User description

What
Update the support URL in NoSuchElementException to use the non-hyphen docs anchor:

• #nosuchelementexception

Why
The Selenium docs use lowercase exception names without hyphens for section anchors.
Old link (#no-such-element-exception) doesn’t match and drops users at the top.

How I tested

• Triggered NoSuchElementException locally and confirmed the message includes:
  https://www.selenium.dev/documentation/webdriver/troubleshooting/errors#nosuchelementexception

Scope

• No changes to other exceptions.

Fixes #16302 16302

🧪 PR contains tests

🔒 No security concerns identified

⚡ Recommended focus areas for review Consistency Verify other exception classes use the correct non-hyphen anchors as well to maintain consistency across the codebase and docs links. private static final String SUPPORT_URL = BASE_SUPPORT_URL + "#nosuchelementexception"; Immutability Consider making the C# support URL field readonly/const (if possible) to match its constant nature and prevent unintended mutation. private static string supportUrl = baseSupportUrl + "#nosuchelementexception";

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
Possible issue	Normalize URL before fragment Normalize the base URL before appending the fragment to avoid producing '.../errors/#nosuchelementexception' when baseSupportUrl ends with a slash. Trim the trailing slash so the generated link consistently matches tests and docs. dotnet/src/webdriver/NoSuchElementException.cs [34] -private static string supportUrl = baseSupportUrl + "#nosuchelementexception"; +private static string supportUrl = baseSupportUrl.TrimEnd('/') + "#nosuchelementexception"; Apply / Chat Suggestion importance[1-10]: 6 __ Why: The suggestion improves robustness by ensuring the constructed URL is always correct, even if the baseSupportUrl has an unexpected trailing slash.	Low
	Strip trailing slash before fragment Guard against a trailing slash in BASE_SUPPORT_URL to prevent generating '.../errors/#nosuchelementexception', which may not match assertions and can vary across environments. Normalize by stripping a trailing slash before appending the fragment. java/src/org/openqa/selenium/NoSuchElementException.java [30] -private static final String SUPPORT_URL = BASE_SUPPORT_URL + "#nosuchelementexception"; +private static final String SUPPORT_URL = + (BASE_SUPPORT_URL.endsWith("/") ? BASE_SUPPORT_URL.substring(0, BASE_SUPPORT_URL.length() - 1) : BASE_SUPPORT_URL) + + "#nosuchelementexception"; Apply / Chat Suggestion importance[1-10]: 6 __ Why: The suggestion improves robustness by ensuring the constructed URL is always correct, even if the BASE_SUPPORT_URL has an unexpected trailing slash.	Low
General	Relax test for optional slash Make the assertion resilient to an optional slash before the fragment to reduce brittleness if the base URL definition changes. Use a regex match that allows an optional '/' before #nosuchelementexception while still validating the full message. dotnet/test/common/RelativeLocatorTest.cs [227] -}, Throws.TypeOf<NoSuchElementException>().With.Message.EqualTo("Unable to find element; For documentation on this error, please visit: https://www.selenium.dev/documentation/webdriver/troubleshooting/errors#nosuchelementexception")); +}, Throws.TypeOf<NoSuchElementException>().With.Message.Matches(@"^Unable to find element; For documentation on this error, please visit: https://www\.selenium\.dev/documentation/webdriver/troubleshooting/errors/?#nosuchelementexception$")); Apply / Chat Suggestion importance[1-10]: 5 __ Why: The suggestion improves test resilience by using a regular expression to handle potential variations in the URL, making the test less brittle to changes in baseSupportUrl.	Low
Learned best practice	Use interpolation and readonly Prefer C# string interpolation for clarity and mark the field readonly to prevent accidental reassignment. dotnet/src/webdriver/NoSuchElementException.cs [34] -private static string supportUrl = baseSupportUrl + "#nosuchelementexception"; +private static readonly string supportUrl = $"{baseSupportUrl}#nosuchelementexception"; Apply / Chat Suggestion importance[1-10]: 5 __ Why: Relevant best practice - Use language-appropriate string interpolation and prefer immutable fields for constant values.
