What article on docs.github.com is affected?

https://docs.github.com/en/actions/using-workflows/caching-dependencies-to-speed-up-workflows#force-deleting-cache-entries

Specifically

What part(s) of the article would you like to see updated?

gh actions-cache list returns up to a limit of 30 caches by default, and one can pass -L 100 to have a limit of 100, so stating the workflow deletes all caches can be incorrect for PRs with many caches.

Additional information

• Feature request to add pagination to gh actions-cache list Feature request: Pagination support actions/gh-actions-cache#75
• gh actions-cache list docs https://github.com/actions/gh-actions-cache#list
• Workaround is to use gh api, e.g. cacheKeysForPR=$(gh api /repos/$REPO/actions/caches?ref=$BRANCH --paginate | jq -r '.actions_caches[].key' )
