Added GitHub CI/CD workflow to generate and release man pages

[alberti42]

Thank you for the amazing utility.

I wanted to be able to install tig directly from your GitHub repo, but I wanted to install on all my linux machines asciidoc to generate the man pages. Thus, I added a GitHub CI/CD workflow that generates the man pages from the asciidoc and then release them automatically. This way, I can install tig directly using zinit.

You do not need to understand the code below if you never worked with zinit. It is just to give you an idea how you can install tig directly. The instruction dl downloads the man pages from the GitHub release page.

zinit ice \
  binary \
  depth=1 \
  wait \
  lucid \
  dl"https://github.com/alberti42/fork-tig/releases/download/latest-man-pages/tig.1 -> $ZINIT[MAN_DIR]/man1/tig.1;
  https://github.com/alberti42/fork-tig/releases/download/latest-man-pages/tigmanual.7 -> $ZINIT[MAN_DIR]/man7/tigmanual.7;
  https://github.com/alberti42/fork-tig/releases/download/latest-man-pages/tigrc.5 -> $ZINIT[MAN_DIR]/man5/tigrc.5;" \
  make \
  id-as'jonas/tig' \
  lbin'src/tig -> tig' \

zinit light @alberti42/fork-tig

I believe other people can find other useful applications of the automatically released man pages.
