chore: update infra ci to run weekly and on release pr (#1124)

## Description

Switches nightly CI to weekly, but also adds `milestoned` trigger to run
this CI pre-release. To date we have seen minimal issues with uds-core
in these environments that have actually been caused by core issues.
Reducing this CI to weekly + before release will still ensure that we
can catch issues, but also optimize our time/cost.

I also added a modification to the cluster wait script to wait on jobs.
Some of our recent CI has failed due to metallb not being installed
completely yet (it is installed via a rancher `helmchart` CR, which
creates a job). Example failure this should resolve:
