Allow retriggering a store submission

[fregante]

This workflow creates a version and then attempts to submit it all at once: https://github.com/fregante/ghatemplates/blob/main/webext/release.yml

It should probably take workflow_dispatch parameter to:

• use the latest release instead of creating a new one
• submit only to a specific store

Docs: https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#onworkflow_dispatchinputs

• use the latest release instead of creating a new one

This might be easiest added as logic into https://github.com/fregante/daily-version-action so it can just fake VERSION_CREATED and the other ENVs

on:
  workflow_dispatch:
    inputs:
      use-existing:
        type: boolean
        description: Skip version generation and use the latest tag

      uses: fregante/daily-version-action@v2
      with:
        use-existing: github.event.inputs.use-existing

• submit only to a specific store

Maybe possible via environments:

on:
  workflow_dispatch:
    inputs:
      environment:
        description: What store to deploy
        type: environment
