Update CODEOWNERS (#41940)

Re-assign the component ownership from `elastic/obs-cloud-monitoring` to `elastic/obs-ds-hosted-services`.

The practical reason is the old `elastic/obs-cloud-monitoring` team only includes a subset of the current `elastic/obs-ds-hosted-services`. So if the person who approves a PR is not included in `elastic/obs-cloud-monitoring`, I have to ping an additional person.
