Add the 'PushEvent' webhook and associated PushCommit object

[drewroengoogle]

• This adds some of the information for the PushEvent from Github
• Additionally, created PushGitCommit that contains some data for the list of commits and head commit for PushEvent

cc @robbecker-wf is it possible to get this into a release?

[robrbecker]

Looking now... sorry for the delay.

Released in version 9.18.0 https://github.com/SpinlockLabs/github.dart/releases/tag/9.18.0

Hi @robbecker-wf, I noticed there is a discrepancy in the Repository object defined in the PushEvent object here and the Repository object we are being sent in the PushEvent webhook, which will cause an error when converting the json to this new PushEvent object. Would it make more sense to revert this change, or instead open a new PR and fix it forward? Let me know your thoughts.

Hmm good question. Would it be easier for Google if we just reverted? I don't see other issues filed with this problem, but that doesn't mean there aren't people out there affected.

Can you revert the change but release the package under the same version as that with the change? That way no one has to update and technically have two versions with the same code?

This would probably be best if possible. I would also rather revert if we can.

Once a version is published to the pub server, it's there. So the revert will have to be 9.19.0

Reverted in #387
published 9.19.0
