Enable website to display status reports

• Switch to workflow/CI based releases instead of branch-based
• Figure out how to keep a submodule or equivalent to https://github.com/rust-gcc/reporting up to date
  • Probably by cloning the repo every-night and redeploying the website?
• Figure out how to translate from org-mode to markdown or have github pages/jekyll display org-mode properly
  ---> This can be achieved by using the gfm export format for pandoc: pandoc --from=org --to=gfm <file>.org > <file>.md

For the last point, note that pandoc screws up the tables as well as some formatting like C++ code-blocks. So we still have some modifications to do (or maybe we can convert org-mode directly to HTML?)

まず GitHub Pages/Jekyll のセットアップと rust-gcc/reporting リポジトリを確認し、次に提案されている workflow/CI release と nightly clone のアプローチを比較します。pandoc の org-to-gfm 変換、特にテーブルと C++ コードブロックを確認します。status reports が自動的に更新され、ウェブサイト上で正しくレンダリングされれば完了です。
