trivial updates on github actions

[mocobeta]

• upgrade actions/setup-java to v2 in the hunspell regression workflow (aligned with the main workflow)
• migrate the distribution to 'temurin' (recommended in supported distributions)

Do you have a minute to take a look? @dweiss

It'd be interesting to randomize those distributions using a custom action, perhaps? I have no experience here whatsoever, but I bet it's possible...

Thank you, I will merge this soon.

I have never tried writing such a complex action, it could be implemented by some bash script. ? (I am not sure the Actions' sandbox gives users what level of flexibility.)

I think these actions are javascript, basically. I've never written one myself, so can't help. Don't worry about it, it was just a wild idea - we have lots of randomization elsewhere.

I am not sure if randomizing the distribution per test run is possible without forking the setup-java action, but I think a matrix test may be easy (if it makes sense to run workflows for multiple distributions on every PR.)
