From its metadata (action.yml) and doc, the Azure/static-web-apps-deploy@v1 action does mark its input app_location required.

As the vscode-github-actions extension knows necessity of inputs from the action.yml of the corresponding action, I think the reported warning is valid, even if the input app_location is actually optional.
