Add updates in groups

[claudioandre-br]

Describe your changes

Correction to make the process more straightforward, start grouping PRs.

By default, Dependabot raises a single pull request for each dependency that needs to be updated. We are going to use groups, so that Dependabot opens a single pull request to update multiple dependencies at the same time.

Fix: 032160d.

My fault, I didn't see a warning in #592.

[claudioandre-br]

Some jobs were not executed in this PR, for example:

• the scorecard was executed in Disable dependency review in forks #600, but not in this Add updates in groups #601.
• the same applies to scan-rootfs and scan-sbom

I can't understand why.

The documentation suggests something like:

  push:
    branches:
      - 'main'

But if the configuration files are wrong, it should always fail.

GitHub may be having a bad day.
