Merge 042eb6c579 into 9967e2caab

Regenerates this repo's CODEOWNERS from cloudnative-pg/cnpg-infra's
`componentowners-policy.yaml`, the org's tracked desired state for
CODEOWNERS content.

- Routes ownership through this repo's dedicated GitHub owners team
instead of hardcoded usernames, so membership changes are picked up
automatically.
- Any path-scoped rule now also includes the repo's general owners, so a
path rule adds reviewers rather than silently replacing the `*` rule's
owners for that subtree (CODEOWNERS only honors the last matching
pattern, it does not merge).

See cloudnative-pg/cnpg-infra for the policy this is generated from.
