Make release process task list more scriptable

[phisco]

What problem are you facing?

Currently the release procedure is mostly pointing to do things via UIs, e.g. run this workflow with these inputs, check this folder contains these files, which is really error prone.

How could UXP help solve your problem?

We could make the checklist a script leveraging tools such as gh to run pipelines, sed to do simple changes, variables to reference the right versions, etc... as discussed in #406
