feat: add task queue (#9321)

# Which Problems Are Solved

To integrate river as a task queue we need to ensure the migrations of
river are executed.

# How the Problems Are Solved

- A new schema was added to the Zitadel database called "queue"
- Added a repeatable setup step to Zitadel which executes the
[migrations of
river](https://riverqueue.com/docs/migrations#go-migration-api).

# Additional Changes

- Added more hooks to the databases to properly set the schema for the
task queue

# Additional Context

- Closes https://github.com/zitadel/zitadel/issues/9280
