Add release please workflow to help with releases

[leikoilja]

So the proposed CI action will:

• collect all commits from main branch into a new PR (example)
• a new release PR will also update all package versions
• once the release PR is merged, the workflow will auto create release (example)

Closes #157

@leikoilja is attempting to deploy a commit to the Coderax's projects Team on Vercel.

A member of the Team first needs to authorize it.

All committers have signed the CLA.

I have come to an conclusion that I don't want this on everything. I would love to have this for self-hosting but not on SDKs and what not since they all have some complex logic when I bump version.

Could we just use release please for self-hosting purpose. Each release will contain all commits from the last time. And bump versions (same version on all) for these packages

• /package.json
• /apps/*/package.json

@lindesvard , sounds about right. I have now pushed a commit with just those files bumped, please re-review :)
