Use ubuntu-latest instead of a hosted 4-core runner

[jeefy]

Description

Heya! Friendly neighborhood CNCF staffer here. The ubuntu-latest runner is already a 4-core runner, so using a hosted 4-core runner is unnecessary (and actually costs money). This PR just swaps any 4-core hosted runners to use ubuntu-latest. There should be zero change or impact, functionally this is a SKU change.

Please reach out to me in the CNCF/K8s slack(s) (jeefy) or via email ([email protected]) with any questions.

Type of change

Replaces ubuntu-latest-m (which is a pay-for 4-core hosted runner) to ubuntu-latest (which is the free 4-core runner with no real spec difference)

Thank you @jeefy !
But it looks like we hit a error running out of disk space with this update consistently. (Following are errors in different runs:)

https://github.com/radius-project/radius/actions/runs/11110614862/job/30941845181?pr=7973

We may have to stay with ubuntu-latest-m for now until we can explore possibilities like cleaning up after steps or other optimizations.

@jeefy - any ideas? We're using kind in the test pipelines to stand up Kubernetes, and then running tests on that cluster.

ubuntu-latest-m has 16 GB RAM. Not sure if ubuntu-latest also has that much.

That could be the reason why one of our functional tests is failing.

[jeefy]

They have the same amount of RAM, but the disk space is different (free runner: 14GB, non-free... 140GB)

I'm going to update the PR to use one of our hosted runners since it has more disk.

Don't know why the job isn't getting picked up, and I watched other jobs outside of this repo during this. I'll have to investigate further. Thanks!
