fix: Exclude Trailing \r from Comment Nodes on CRLF-Formatted Files

[felix-andreas]

Currently, when parsing files with CRLF (\r\n) line endings, comment nodes incorrectly include the trailing \r character.

This PR updates the grammar to exclude \r from the comment node content, aligning the behavior with other grammars such as tree-sitter-javascript.

Example Input

# comment

Output of tree-sitter parse

Before this PR

(program [0, 0] - [1, 0]

Using this PR

(program [0, 0] - [1, 0]
