[FTR][Ownership] add @elastic/response-ops to es archives (#193449)

## Summary

Modify code owner declarations for @elastic/response-ops team in
`.github/CODEOWNERS`

### Update for Reviewers
With the merge of [this](#193277),
you can now do this:
`node scripts/get_owners_for_file.js --file
x-pack/test/functional/es_archives/action_task_params`

```
 succ elastic/response-ops
```
_So, you can use this script to see if the code owners file is reporting
erroneously_

### For Reviewers
Added these lines:
```
/x-pack/test/functional/es_archives/actions @elastic/response-ops
/x-pack/test/functional/es_archives/alerting @elastic/response-ops
/x-pack/test/functional/es_archives/alerts @elastic/response-ops
/x-pack/test/functional/es_archives/alerts_legacy @elastic/response-ops
/x-pack/test/functional/es_archives/observability/alerts @elastic/response-ops
/x-pack/test/functional/es_archives/actions @elastic/response-ops
/x-pack/test/functional/es_archives/rules_scheduled_task_id  @elastic/response-ops
/x-pack/test/functional/es_archives/alerting/8_2_0  @elastic/response-ops
```

Most of these changes come from searching for `esArchiver.load`, within
`x-pack/test/alerting_api_integration`
Obviously this can easily be erroneous, so please keep me honest.

#### Notes

This is a best guess effort, as we march towards having zero files
within `test` && `x-pack/test` && `x-pack/test_serverless` without a
code owner.

In the end, this will contribute to better reporting.
