fix: resolve the open CodeQL alerts (#156)

Strip HTML tags and XML comments until the text no longer changes, so that
nested input cannot reassemble a tag or comment after a single pass
(js/incomplete-multi-character-sanitization in website/.eleventy.js and
website/scripts/validate-version-info.js).

Limit the GITHUB_TOKEN of the PR compile check and the test version-XML
workflow to read access (actions/missing-workflow-permissions).
