feat: add new command 'data:pg:levels'

[sbosio]

Summary

Here we add a new data:pg:wait command, similar to addons:wait and pg:wait, specific for Advanced databases.

The implementation was mostly copied from https://github.com/heroku/heroku-cli-plugin-data-beta/pull/176, converted to @oclif/core v4 and ESM, with minor refactor and fixes.

This is targeted right now to be merged against v11.0.0 branch, but we really be merging this to main after v11.0.0 branch has been merged to main and the final Heroku CLI v11.0.0 released. We're targeting to merge and release this soon after that on v11.1.0. We're keeping this as a draft PR until that time to avoid merging accidentally on v11.0.0.
