This PR is a follow-up to https://code.forgejo.org/forgejo/runner/pulls/1117. That PR has to be merged before this one can proceed.
The objective is to allow referencing the `inputs` context in `jobs.<job_id>.runs-on`. That enables users to enter a label in the Forgejo UI during `workflow_dispatch`.
Example:
```yaml
name: test
on:
workflow_dispatch:
inputs:
image:
required: true
type: string
jobs:
test:
runs-on: ${{ inputs.image }}
steps:
- run: echo "Running on ${{ inputs.image }}"
```
Using `inputs` with reusable workflows does not work. I haven't changed `schedule_tasks.go` because the `schedule` trigger does not support `inputs`.
