Skip comments in Ruby files when checking for class names

[thecrypticace]

Fixes #19239

[coderabbitai]

Walkthrough

Adds an Exclamation enum variant and updates the arbitrary-property parser to treat a top-level exclamation mark as invalid (e.g. [color:red!], [color:red!important]). Enhances the Ruby pre-processor to skip single- and double-quoted string contents with backslash escapes, convert # comments to spaces until newline, and refine %w, %W, %p delimiter handling using a bracket stack and adjusted space/newline boundary rules. Removes nonfunctional annotation lines from a HAML test fixture and adds CHANGELOG entries for the Ruby comment and top-level ! changes.

Pre-merge checks

✅ Passed checks (5 passed)

Check name	Status	Explanation
Title check	✅ Passed	The title 'Skip comments in Ruby files when checking for class names' accurately reflects the primary change in the PR—improved Ruby preprocessor comment handling.
Description check	✅ Passed	The description 'Fixes #19239' is concise and references the linked issue that provides full context about the PR's objectives.
Linked Issues check	✅ Passed	The PR addresses issue #19239 by skipping RDoc comments in Ruby files (ruby.rs) and handling top-level exclamation marks in arbitrary properties (arbitrary_property_machine.rs), both of which suppress the parsing warnings described in the issue.
Out of Scope Changes check	✅ Passed	All changes are in-scope: improved Ruby comment/string handling, top-level exclamation mark detection for arbitrary properties, fixture cleanup, and changelog updates directly address the RDoc parsing warning issue.
Docstring Coverage	✅ Passed	Docstring coverage is 80.00% which is sufficient. The required threshold is 80.00%.

Looks good, but not sure about the !important.

Can you also add a changelog entry?

[thecrypticace]

Yeah I was not gonna change that part. It's unrelated anyway. Will get the change log updated.
