Preset manual triggers or trigger documentation

[Limess]

Description

It'd be useful for some ad-hoc/manual workloads to be able to define structure for the JSON used in manual triggered.

This could be either a JSON schema, example/presets trigger payloads, or both.

Use case / motivation

For some use cases we allow triggering jobs with different parameters manually, e.g. disabling some notifications, or triggering more debug logs, or a a different behaviour.

As the manual trigger UI is fairly basic, there's no way of hinting this to users (aside from documentation in the code/UI, however the DAG level documentation is not shown on the manual trigger page so this is of little help at the time of triggering).

Yes, thanks for pointing this out. I'll sub to that issue and close this.
