Add support for Arch User Repository (AUR)

[Aniket-Pradhan]

If an incorrect URL is opened, please provide the following so we can write a test:

Example clone URL:

https://aur.archlinux.org/git-open-git.git or ssh://aur@aur.archlinux.org/git-open-git.git

Example branch name:

master

Expected web URL:

https://aur.archlinux.org/packages/git-open-git

It will be a simple fix. We can add a simple if condition with a regex to check if the URL is of the AUR, and if it is, we just need to append the /packages/ part to the URL.

For example,
URL opened by git open: https://aur.archlinux.org/git-open-git
Actual URL: https://aur.archlinux.org/packages/git-open-git

if [ $domain == "aur.archlinux.org" ]; then
  domain="$domain/packages"
