Docs: Update documentation for 2.7

[khsrali]

Our RTD: https://aiida.readthedocs.io/projects/aiida-core/en/stable/
Only updates by each aiida-core releases..
Therefore before each release, we may update our documentation according to the merged PRs

[agoscinski]

@khsrali This is very unspecific. One can go through all documentation issues buy filter for the documentation label. But then it is overwhelming. So please specify here doc issues that should be fixed by the next release, otherwise I think this issue can be closed as it serves no purpose.

Mainly

• Stashing -> @khsrali -> Doc: Add StashCalculation explanation to RTD #6861
• Dumping -> @GeigerJ2
• Installing dependencies using uv? -> @danielhollas see this comment from a contributor Moved to Improvement in Wiki #6801
• ForceKill -> @agoscinski Doc: Update the RTD regarding verdi process {kill|pause|play} #6909

[khsrali]

@agoscinski Why is this 2.8 ? I believe should be 2.7.1 or 2.7.2?
We should document how to use what we release 😄

Installing dependencies using uv? -> @danielhollas see #6847 (comment) from a contributor

I don't see this in the RTD. I would separate issues into Wiki updates which we can immediately update and doc updates which only only keep updated with a release. I move it somewhere else

ForceKill -> @agoscinski

I don't think we need RTD for force kill. It is a CLI command and is explained in the help page there.
EDIT: Little did I know, that there is verdi process {play|pause|kill} is in the RTD, I made a PR for updating it.

Yeah, uv stuff is more for developers not users. Note that we've been discussing moving at least part of the wiki into internal docs in the repo itself, since it is then much easier to keep up to date. I can handle the uv part once I have a bit more time, probably by the and of June.
