Fixes issue #99:Quarto Preview Fails on Windows (OS error 123) Due to Hugo Shortcode in _quarto.yml

I’ve closed the previous PR because it unintentionally included an incorrect .gitignore change. To keep the contribution clean and focused, I’ve opened a new PR for the same issue with only the relevant fixes applied.

This PR addresses Issue #99: Quarto Preview Fails on Windows (OS error 123), which was caused by the formatting of the margin-header configuration in _quarto.yml. After testing, _support-button.qmd works correctly as-is; the issue originated from how the YAML entry was defined, not from the support button file itself.

What this PR changes:

• Replaces the multiline | YAML block with a single quoted string to prevent misinterpretation of special characters and indentation on Windows.
• Ensures the file is saved in UTF-8 encoding to avoid parsing issues related to Windows default encodings.

Result:

• The support button renders correctly
• The Windows “123” OS error is resolved
• No changes are required to _support-button.qmd

Thank you very much for your patience and understanding.
