feat(ci): Add nightly deploy for main and recent release branches

[squakez]

It would be nice to self update the branches as we do during the bump phase:

camel-k-runtime/scripts/release-branch.sh

Line 38 in 48043b8

# Support nightly CI tasks

- feel free to take it as a follow up actions to make sure this is working as expected after first nightly push.

Alternatively, consider to add a new step to the existing https://github.com/apache/camel-k-runtime/blob/main/.github/actions/automatic-updates/action.yml we may have a simpler maintenance with a single running action.

I definitely prefer using a pre-existing update workflow. I moved the code. We'll see how it goes.
