Relax the 10-parameter input limitation on workflow_dispatch

Describe the bug

Workflows with more than 10 parameters are considered invalid. Crucially, this also applies to reusable workflows used from a workflow that could be dispatched manually.

To Reproduce Steps to reproduce the behavior:

1. Write a workflow with at least 11 inputs
2. set it to run on: { workflow_dispatch: }
3. See error upon execution

Expected behavior The workflow does not trigger errors

Runner Version and Platform

Current GHA hosted runner

What’s not working?

 Check failure on line 1 in .github/workflows/build-and-deploy.yml

GitHub Actions
/ .github/workflows/build-and-deploy.yml
Invalid workflow file
handling usage of workflow "DanySK/workflows/.github/workflows/build-and-deploy-gradle-project.yml@master": workflow is invalid: you may only define up to 10 `inputs` for a `workflow_dispatch` event

Note: I am not sure that runner is the correct repository for reporting this. Please let me know if I should open the issue report elsewhere.

The problem is also being discussed here.

We’re also bumping into this. Our use case is using composite action and it requires many optional configuration options.

One workaround is to accept a JSON payload and deserialize within an action, but that’s pretty nasty and error prone when triggering from the UI.

The limit should be at least 25 to cover most use cases.

Please report this to https://github.community/c/code-to-cloud/github-actions/41 the runner itself has no control over this limitation.
