Enable collection integration tests on GHA

There are a number of changes here:

- Abstract out a GHA composite action for running the dev environment
- Update the e2e tests to use that new abstracted action
- Introduce a new (matrixed) job for running collection integration
  tests. This splits the jobs up based on filename.
- Collect coverage info and generate an html report that people can
  download easily to see collection coverage info.
- Do some hacks to delete the intermediary coverage file artifacts
  which aren't needed after the job finishes.
