[damdo]

What type of PR is this?
/kind feature

What this PR does / why we need it:

CAPI v1.9.0-beta.0 is out now, so this PRs bumps the CAPI version used by CAPG to it.

Bumps CAPI to v1.9.z based on https://github.com/kubernetes-sigs/cluster-api/blob/main/docs/book/src/developer/providers/migrations/v1.8-to-v1.9.md

Special notes for your reviewer:
api-diff failing is expected as the API changed to a typed go generics function.

Checklist:

• squashed commits
• adds or updates e2e tests

Release note:

Bump CAPI to v1.9.z
