Bring project files up to date

[llucax]

Probably some upgrading of templates was missed while updating repo-config.

This should fix the currently failing CI checks in arm.

This needs a few branch rules updates to pass the checks, but I will wait until it is approved to make them, otherwise we'll block merging other PRs.

@eduardiazf FYI, although you are probably not very familiar with all these workflows and config, so maybe @Marenz can do a quick review. I basically copy&pasted files from other projects so it is nothing new really...
