docs: adapt regtests README.md to Quarkus

Note: this assumes #610 is merged as is.

nit: whitespace

This seems extremely unintuitive. Is it too late to fix this?

[eric-maynard]

To be clear, we shouldn't block the doc change on this behavior -- but if we could fix this behavior that would be great.

I think this paragraph is written in a very anxiety-provoking tone. It's not that unnatural for developers to first build their code, then start end-to-end tests. Let me rephrase this and I think it could sound a lot more intuitive.

I personally find the propose change to be ok, but willing to see an alternative.

[adutra]

Let me know if that's better.

mega nit: minikube

[eric-maynard]

Is this intentional?

[eric-maynard]

Seems like a spurious change?

[adutra]

IntelliJ says it's incorrect:

[eric-maynard]

IntelliJ says it's less concise in your screenshot which is true, but it's not incorrect and it's not exactly the same.

[adutra]

Okay, reverting.

[dimas-b]

I wonder if it's locale specific 😅

[dimas-b]

LGTM overall 👍

rm -rf ./regtests/output/* simpler (without &&)? Does it work (not tested :) )?

There has been some confusion around regression tests lately (see #865) and I think this PR would help. So I'm going to merge it now. If there are leftovers, please speak up and I will fix in another PR. Thanks!
