Consider using `mikepenz/action-junit-report` to annotate results on PRs

[G-Rath]

It's easy enough to have rspec output results in junit format, which we could combine with mikepenz/action-junit-report to annotate failing specs

(we could also use this with rubocop as that supports outputting junit too)

I'm assuming are the same kind annotations that our eslint setup already supports. I must admit that I personally don't find much value from them but that might just be me 🤷 Happy to go with what the consensus wants here.

i personally find it easier to read the output in the log as it's the same as what i am used to when running tests locally, i don't mind the addition but i'm unlikely to look at them

I'm removing ready for dev label for now. I don't think we have much consensus that this feature would be particularly useful. More discussion needed.

[G-Rath]

@eoinkelly we marked this as ready for dev because we got consensus - I believe overall it was more that there weren't any strong disagreements or downsides not to rather that more than a minority would find it useful, but it was consensus none the less.

Fwiw I feel like this was at a guild meeting while you were on leave, but maybe you were there..?

I'll do a PR this week and we can start using it on a few projects.

I've created ackama/aws_ec2_environment#9 to showcase this in action
