ci(tag): dispatch Renovate on tf-depl-kubernetes once the release image is pushed

A release only reached perso_private/tf-depl-kubernetes on the next hourly
Renovate scan, so the image bump PR could lag up to an hour behind the tag.

After the image push completes, dispatch that repo's Renovate workflow through
the Gitea API (workflow_dispatch is already enabled there). It authenticates
with the RENOVATE_TOKEN org secret of this organisation — the same token the
Renovate instance itself uses, no extra credential. The job fails loudly so a
rotated token shows up instead of the trigger silently going missing.
