[auto-publication] clean up old builds from the local maven repository

[grigoryk]

A mirror of the same issue in A-C: https://github.com/mozilla-mobile/android-components/issues/11413

The patch for A-C simply removes contents of ~/.m2/repository/org/mozilla/components before publishing. Perhaps the same approach could work here as well (but for ~/.m2/repository/org/mozilla/appservices)? Need to double-check if every local publication publishes all of the necessary artifacts (in which case, we should be able to just blow away repository/org/mozilla/appservices).

SGTM - I rm that dir manually as a matter of course anyway.
