## What changed? <!-- Describe what has changed in this PR --> Replace `golang.org/x/exp` with stdlib where possible. Unfortunately, `maps` doesn't provide all methods that `expmaps` does, so I still have `golang.org/x/exp` in `go.mod`. ## Why? <!-- Tell your future self why have you made these changes --> Follow up to #6018. ## How did you test it? <!-- How have you verified this change? Tested locally? Added a unit test? Checked in staging env? --> Build. ## Potential risks <!-- Assuming the worst case, what can be broken when deploying this change to production? --> No risks. ## Documentation <!-- Have you made sure this change doesn't falsify anything currently stated in `docs/`? If significant new behavior is added, have you described that in `docs/`? --> No. ## Is hotfix candidate? <!-- Is this PR a hotfix candidate or does it require a notification to be sent to the broader community? (Yes/No) --> No.
