'cleanup caches' example workflow is wrong and harmful!

[andreasabel]

It will delete the caches of the base branch, not the PR branch. Needs fixing! I added an alert in comments that this example doesn't work.

Evidence here: https://github.com/agda/agda/actions/runs/4025940394/jobs/6919801891#step:3:5 (Note: these logs will be removed by github after some time.)

@andreasabel Thanks so much for opening a PR! I'll get this triaged for review :zap:

@andreasabel Actually after looking at it, this PR would be better opened as issue as this is a report of a discrepancy. So I'm going to go ahead and close this PR. 💛

Would you mind taking the information in your note and creating a new issue with it? Then I can get this properly triaged and up for review 👍

@cmwilson21 : Ok, Courtney, I opened an issue instead:

• #23600

(This is my first report here, so I don't know my ways around here yet. Initially, I followed the "Contribute" button in the docs which brought me to the editor to open a PR.)

@andreasabel Sounds great! Take a look at the contributing.md if you want to explore further for future contributions 😄
