ci: Review GHA pipeline

[gpmayorga]

Description

This pull request...

• Upgrades all available external GH Actions to newer versions.
• Upgrades the node version of Gcloud functions from v18 to v20 as it deprecates in April
• Configures dependabot to catch new GHA version packages monthly (needs activation in setitngs of the repository)
• Fixes a bug where production deployments might fetch from the wrong artifacts
• Fixes small typo, linting and syntax issues in the workflow files
• Removes catalyst deployment
• Removes deployment of functions for environments: fast-forward (main) & development.
• Add new OWNERS to make sure we have at least 3 as at least 2 are needed to approve a PR (the one creating the change and a reviewer)
• Changes how prod is deployed which now will:
  • Fetch the artifacts form the relese assets
  • Allow to specify a tag that has been released in the past to roll back prod.

Impact

Lots of small changes that should not change the pipline behavior but critical changes were made to:

• Prod deployment, needs testing to make sure it works as intended (needs to be merged first)
• Function deployment masked under NEVER_USED which was causing an actual NEVER_USED function to be deployed in Google repeatedly, causing a lot of worflows to fail (look at main branch commits mostly all red)

Pending testing

• Test the release workflow for production (needs merging to main first)
• Test the pinning and onboarding functions (upgraded to node 20)
