Updated the regular expression to match <link> tags with the canonical rel attribute regardless of attribute order, improving robustness in canonical link detection.

This pull request adds support for autofixing the
link-rel-canonical-requirerule in the HTMLHint extension, allowing the extension to automatically insert a canonical link tag into the<head>section of HTML documents when it is missing. The feature is documented in both the changelog and README, and new tests have been added to ensure correct behavior.Autofix Feature Addition
createLinkRelCanonicalRequireFixfunction inhtmlhint-server/src/server.ts, which generates a quick fix to add a<link rel="canonical">tag to the<head>section if it is missing. The function intelligently determines the best insertion point based on existing meta tags and respects thetag-self-closerule.createAutoFixesfunction so that diagnostics for thelink-rel-canonical-requirerule now trigger the autofix logic.Documentation Updates
htmlhint/CHANGELOG.md).link-rel-canonical-requireas a supported autofix rule.Testing and Configuration
link-rel-canonical-requirerule in the test configuration (test/autofix/.htmlhintrc).test/autofix/link-canonical-test.html) to verify the autofix behavior for canonical link tags.
