This changes to publish TED's canonical app port, `4200`.
What's wrong with the currently used ports?
57f63003ef/app/app.ts (L18-L20)
Quoting here:
> 8000, // Past static webserver port, to be removed, after switching to
4200, clashes with CloudServices on CI.
> 5000, // Past Postgraphile port, to be removed, after switching to
4200, clashes with macOS AirDrop.
> 3000, // Past Gitea port, to be removed, after removing Gitea, because
it clashes with `yarn start` in Appsmith.

## Summary by CodeRabbit
- **New Features**
- Integrated a new workflow step to validate tags in pull requests,
providing guidance for corrections and halting the workflow if tags are
incorrect.

This is to make it apparent what TED tag was used to run a workflow, so
that runs that happened with an unstable (non `latest`) tag of TED
aren't taken seriously.
Change TBP Schedule
