fix: git URI matching for GitHub fallback

[notorious-gay]

This allows the user to use this action to pull a glitch.com repo to GitHub as they too do not use the .git suffix :+1: (As well as many other origins thanks to @wei's suggestion!)

After wrangling with docker and GitHub not running the action correctly I've got this working, please note the following additional changes had to be made to get the regex to work:

• [X] Add bash to alpine's installed applications via the Dockerfile
• [X] Switch to bash for the sh scripts

Please let me know if you have any questions or suggestions 😄

This change has been tested to work with the following URI's:

https://user@api.glitch.com/git/project
git@github.com:repo-sync/github-sync.git
http://user@api.glitch.com/git/project
repo-sync/github-sync
ssh://user@host.xz:port/path/to/repo.git/
ssh://user@host.xz/path/to/repo.git/
ssh://host.xz:port/path/to/repo.git/
ssh://host.xz/path/to/repo.git/
ssh://user@host.xz/path/to/repo.git/
ssh://host.xz/path/to/repo.git/
ssh://user@host.xz/~user/path/to/repo.git/
ssh://host.xz/~user/path/to/repo.git/
ssh://user@host.xz/~/path/to/repo.git

user@host.xz:/path/to/repo.git/
host.xz:/path/to/repo.git/
user@host.xz:~user/path/to/repo.git/
host.xz:~user/path/to/repo.git/
user@host.xz:path/to/repo.git
host.xz:path/to/repo.git
rsync://host.xz/path/to/repo.git/
git://host.xz/path/to/repo.git/
git://host.xz/~user/path/to/repo.git/
http://host.xz/path/to/repo.git/
https://host.xz/path/to/repo.git/
https://user@host.xz/path/to/repo
https://user@host.xz/path/to/repo.git

Wow thanks so much for the PR! Instead of adding bash as a dependency, we could just use grep regex match.

if ! echo $UPSTREAM_REPO | grep -Eq ':|@|\.git\/?$'
then
  UPSTREAM_REPO="https://github.com/${UPSTREAM_REPO}.git"
fi

Also updated the regex a bit to cover something like host.xz:/path/to/repo too.

If you don't mind, could you pls review my change and perform some quick tests with the url examples you provided above?

No worries, I'll give this a try and get back to you!

All passed and running correctly on my test repo, looks like we're good to go! 🎉
