Describe the feature or problem you’d like to solve

It's not possible to trigger Github Actions from the CLI. This would drastically improve how I manually trigger release workflows.

Documentation GitHub Actions: Manual triggers with workflow_dispatch

It is already possible to do this from the website, so it should be possible from the CLI

Proposed solution

Add gh workflow run <workflow name> -b <branch> which starts of workflows registered with trigger workflow_displatch for a specific branch

Workflows may have custom-defined inputs. It must be possible to specify those as well but I'm not aware of an elegant CLI api. One solution is -Parg1=foo -Parg2=bar as used by gradle.

on: 
  workflow_dispatch:
    inputs:
      logLevel:
        description: 'Log level'     
        required: true
        default: 'warning'
      tags:
        description: 'Test scenario tags'
