Add GitHub Action to run composer outdated and composer audit

[mrdavidburns]

We have noticed on some projects that Renovate is not picking up major version upgrades or we have pinned versions that are not getting new releases. We would like to have a GitHub action that we can run on a weekly or monthly basis so that anyone with access to the logs of that job can identify these packages then we can create tickets to get those packages updated.

@mrdavidburns is this not fixable by changing renovate's configuration?

[mrdavidburns]

@justafish Yes, and we do have that configured for things like Drupal core major and point releases.
I created this when reviewing all our LSM projects and was running those 2 commands to determine if anything was being missed. It doesn't take long to checkout the latest code and run these commands manually. I was thinking this could be helpful to avoid having to do that step, but agree it probably isn't needed for all projects using Drainpipe.

Closing.

There have been cases where renovate did not alert us. I'll share a slack link in our internal devops channel.
