Some GitHub Actions workflows not running in some branches and forks

[astrogeco]

Describe the bug
Workflows only run in the main branch of a forked repo for submodules (and maybe the bundle as well)

To Reproduce

1. Create a new branch in nasa repo or fork
2. Push a change to the branch
3. Observe GitHub Action Workflow dashboard and notice that workflows DO NOT run for your new branch

Expected behavior
Workflows should run for branches in forks and in nasa repo

Code snips
Probably due to this section in our workflows

on:
  push:
    branches:
      - main
  pull_request:

System observed on:
Ubuntu 18.04 (github workflows runner)

Additional context
Can be worked around by creating a pull request on your fork that targets the branch you're working on
