feat(build): use jekyll and restyle website

[ReenigneArcher]

Description

This PR moves the website to a Jekyll build.

Todo:

• update build workflow
  • This build works, but could be simplified... investigate... https://github.com/ReenigneArcher/beautiful-jekyll/blob/b8e13290831a3160751761ecce52800c694560f3/.github/workflows/ci.yml#L59-L72 ... e.g. there would be no gh-pages branch
• fix some colors (see support.html)
• add beautiful-jekyll as a submodule, create workflow/re-usable action that combines the submodule files with our common files, and the target files (for subprojects like Sunshine and GameDB)
• remove dist directory
• add privacy/terms
  • links in footer
• convert readme to markdown
• run workflow when new posts are added to master branch?
• remove discord widget from discord.html page
• hide titles on some pages, and add title to pages that don't have it (e.g. discord.html)
• update gh-pages from other repos that use assets from the published site (move them to jekyll build)
  • Sunshine (docs(gh-pages): migrate site to jekyll format Sunshine#3517)
  • ThemerrDB ... (archived)
  • GamesDB (docs(gh-pages): migrate site to jekyll format GameDB#169)
  • dashboard (optional): https://github.com/red-data-tools/jekyll-jupyter-notebook
• update any projects that use assets from the published site
  • Sunshine
  • Themerr-plex (discord widgetcrate) ... (archived)
  • ThemerrDB (gh-pages) ... (archived)
  • GamesDB (gh-pages) docs(gh-pages): migrate site to jekyll format GameDB#169
  • Themerr-jellyfin? widgetbot?
  • .github (readthedocs)
  • Dashboard
• probably wait for bs5 before merging this: build(deps): bump bootstrap from 4.4.1 to 5.5.3 daattali/beautiful-jekyll#1375
• misc
  • update first blog post date
  • .well-known directory is not included
  • release notifier to create a new blog post automatically
  • don't search all pages (if possible)... only search blog posts
  • better 404 page
  • remove feedback page (point to GitHub discussions instead)
  • clean up comments in _config_theme.yml
  • update re-usable action to accept an artifact instead of checking out the full repo
  • use giscus instead of utterances, with custom css (depends on fix(giscus): add missing attributes and allow local theme daattali/beautiful-jekyll#1407)
    • https://github.com/search?q=repo%3Adaattali%2Fbeautiful-jekyll%20giscus&type=code
    • https://giscus.app/
    • https://giscus.app/themes/custom_example.css
• Readme
  • Badges on readme
  • update readme for using workflow_call action
• rss notifications: feat: monitor rss feed from LizardByte website community#616

• The key 'navbar-var-length' seems to be a typo. It should be 'navbar-var-length'.
