[TASK] Add GIT URI to Slack webhook (#313)

Currently only a composer key is emitted in the slack hook. However, a
URI to the actua GIT repository would be helpful, because:

1.) A composer package may not have been released (yet) of an extension
2.) A TER package may not have been released (yet) of an extension 3.)
The composer key and the Github Repo vendor/name may differ

This commit is unverified. I am crossing my fingers that
`$jar->getRepositoryUrl()` really holds what I expect it to. :-D
