Restore conventional commits action

[ccorda]

We used to have conventional commits enforced, can we get that back for this, bubs-timber, and also our private fired-up-launch repo?

I found out what happened to the old one! https://github.com/zeke/semantic-pull-requests It died with Heroku's free tier. Zeke recommended https://github.com/Ezard/semantic-prs which can be installed via marketplace here: https://github.com/marketplace/semantic-prs. I like this technique since we're not hardcoding actions that would apply to cloned copies of bubs-next.

Looks like it's already working! Moving this to "In Review"
