Nighly build running each month using the dev branch

[joanhey]

As the scheduled only run in the master branch, we update the master nightly run and using the development branch.

We also need to remove the Ubuntu 20.04 (EOL May 31, 2025), as we have done in the dev branch.

The Ubuntu 20.04 runner image will be fully unsupported by April 1, 2025. To raise awareness of the upcoming removal, we will temporarily fail jobs using Ubuntu 20.04. Builds that are scheduled to run during the brownout periods will fail. The brownouts are scheduled for the following dates and times:

March 4 14:00 UTC – 22:00 UTC
March 11 13:00 UTC – 21:00 UTC
March 18 13:00 UTC – 21:00 UTC
March 25 13:00 UTC – 21:00 UTC
What you need to do

Jobs using the ubuntu-20.04 YAML workflow label should be updated to ubuntu-22.04, ubuntu-24.04 or ubuntu-latest. You can always get up-to-date information on our tools by reading about the software in the runner images repository. Please contact GitHub Support if you run into any problems or need help.

We need to merge the development branch in the master.

The only changes now, are about the github actions runners.
