Broken due to an update to Nimble 0.16.2 for the version-2-0 branch.
This PR sets the ref to the previous commit. Also, updates the key
naming so it fits better.

# Important Note
In this PR some required job's names were changed. They need to be
updated at repo-level so this PR can be merged.
The main motivation was to update the Ubuntu version on the daily job as
it seemed it wasn't supported anymore.
macOS 14 fails immediately with no error msg, so we are using 13 for
now.
