Review Comment:
In the legacy api this is a `PUT` I believe. Also it is really dedicated to
the `update_dag_run_state`. It is not a general 'updage_dag_run`.
`@dag_run_router.put`
A general `PATCH` would be missing the `update_mask` etc... (cf legacy and
other PATCH endpoints)

Review Comment:
I think we can drop the `Form` in the name. This is not called from an http
form anymore. (I guess this is where the name is comming from)

Review Comment:
Cf the legacy implementation. Setting a DagRun state has side effect and
should be using the utility functions `set_dag_run_state_to_success`,
`set_dag_run_state_to_queued`, etc... We cannot just set the `DagRun.state`
value in the db.
Also we should also use the DagBag for consistency
