Feature/add missing migrations file check

[arnav13081994]

Description

Added a local pre-commit hook that fails in case the user forgot to commit a migration file.

Checklist:

• I've made sure that tests are updated accordingly (especially if adding or updating a template option)
• I've updated the documentation or confirm that my change doesn't require any updates

Rationale

[browniebroke]

I'm -1 on this. I don't think pre-commit is the right place to check for that.

Also, from the template maintenance perspective, this file if free of templating logic, which enable us to run pre-commit autoupdate to keep versions up to date. Accepting this PR would break this workflow. I think the trade-off is not worth it.
