Move startGroup/endGroup constructs to individual fields

[erikmd]

• Kind: fix
• Closes New fine-grained customization does not allow groups within each section #34

Impact:

• this slightly changes defaults values w.r.t. v1.2.0
• but this is fully backward-compatible w.r.t. v1.1.0
• and this makes it possible to customize group names (that cannot be nested)

I can readily do a point release if you want @tchajed ; otherwise tomorrow Saturday :)

LGTM, thanks!

Up to you when to merge - I already effectively did this by overriding custom_script, once this is merged I can stop doing that.

[erikmd]

BTW I've added some extra documentation on startGroup/endGroup (to document that they not only create foldable groups using the standard GHA feature, but also compute the intermediate elapsed time).

I'd like to merge this PR ASAP as it is a fix, however I'd be glad to have some review for the doc I have added (in a2a4cb7)

Cc @Zimmi48 FYI

In the meantime, note that even if this PR is not yet merged, the docker-coq-action can already be used as is by specifying the temporary branch fix-groups:

- uses: coq-community/docker-coq-action@fix-groups

[Zimmi48]

LGTM but please fix the example overriding before_script, script and uninstall to create groups (in particular, this would replace the echo Workaround...).

[erikmd]

Fixed, and will now release v1.2.1. Thanks @Zimmi48 for your review!

Release done: https://github.com/coq-community/docker-coq-action/releases/tag/v1.2.1; so you'll be able to use the default custom_script from now on :)

Thanks @erikmd, I'm now taking advantage of this in Perennial.
