chore: test cleanup of unneeded folders (#1449)

## Description

When running `npm test` the `pepr-test-module` is created with journey
tests are run on module. This is a common place to test new features in
the controller. However, there was legacy folders being left in the
`dist` folder after the test ended. This PR cleans up the legacy folders
that are no longer needed after the test ends and not relevant for
controller testing.

End to End Test:  <!-- if applicable -->  
(See [Pepr Excellent
Examples](https://github.com/defenseunicorns/pepr-excellent-examples))
