Action not compatible with Open API v3.1.0

[iwaneds23]

Running the action against an Open API Schema results in the following error

Schema Loading Error
The provided schema uses Open API 3.1.0, which is currently not fully supported

Hi! Thanks for reporting!

The CLI output also should have a recommendation on how to proceed:

Proceed with --experimental=openapi-3.1. Caution: May not be fully supported.

In GitHub Action it equates to adding:

    args: '--experimental=openapi-3.1'

Let me know if it helps and if the CLI output misses that suggestion which should immediately follow the message you've shared. Otherwise, I think I can also add some section on troubleshooting to readme + Schemathesis docs (though likely for the next major version already).

P.S. Schemathesis v4 will support Open API 3.1 by default
