Run phpunit or pest depending on the project

Remove the `p` and `pf` aliases that previously only worked for PHPUnit,
and re-add them as functions that run either PHPUnit or Pest PHP based
on the project dependencies.

The checking is done within the `phpunit-or-pest` script and then used
within the new `p` and `pf` functions.
