Add new actions for reasoned diffs and rebuilding imports ("ontobot")

[cmungall]

@balhoff set up a jenkins job for GO that will rebuild extracted import modules and make a PR.

https://gist.github.com/balhoff/6c0d434b1601de4d4006bff76b858ac1

On slack he mentioned it would be possible to translate this to a github action.

He also set up a github action for doing a reasoned diff as a PR:
https://github.com/geneontology/go-ontology/blob/master/.github/workflows/inference_diff.yml

It would be great to have both actions available in the template

I am not sure if there are other considerations

• should it be throttled, e.g. certain kinds of changes could generate very large markdown files
• we only want the import diff to run under some circumstances

Which is about having a github action to make a draft release

I think the two could be separate actions. The diff action can run on an import update PR just as it runs on user edit PRs. No reason to mix the diffing into the import update.
