Update pynn-brainscales to "rc2"

That's the first version that should really work :). rc1 experienced scheduling problems when multiple users were accessing the same hardware resource in parallel.

mentioned in commit 12aa4dbc

Hi just merged.

Hope it works.

sidenote: as i mentioned in my email yesterday the way forward would be to submit your contributions from your personal fork of this repo and not from branches created in this repo. We can continue like this until the first release but then i aim to do a branch clean up. Thanks!

Thanks, and ACK, I read the mail and yes, I agree :D — but I wasn't really thinking about this when creating the request ;).

It's fine :) I know, that is why i suggested that this happens after the current work. Let's hope that this version will do the trick!!

Can you check? https://gitlab.ebrains.eu/technical-coordination/devops/platform/ebrains-spack-builds/-/pipelines/13535

It reports " All of the packages are already installed " a rebuild was not triggered because specs did not change? or it works?

I checked and you're right, spack was satisfied with SOME version of pynn-brainscales being already installed — which was probably fine (but not what I intended) → I did not force it to update the version → !21 (merged)…
