Correctly parse line comments on Windows/CRLF line endings

[sebastien-marichal]

line_comment was incorrectly including the \r character on file using CRLF (Windows).

This change updates the regex in the line_comment rule to explicitly exclude \r along with \n, changing the match pattern from /[^\n]*/ to /[^\r\n]*/.

I was not able to add a test in corpus. I tried to use the :cst attribute with no avail so I could assert node length.

Given the following file (with CRLF):

// test comment

Here the previous parse value:

0:0  - 1:0    parser_output
0:0  - 0:16     line_comment `// test comment\r`

Now with the fix:

0:0  - 1:0    parser_output
0:0  - 0:15     line_comment `// test comment`

Command used for the output: tree-sitter.exe parse --cst .\test.crlf.cls
