security: set-output cmd deprecated. Use $GITHUB_OUTPUT env file (#9287)

* security: `set-output` cmd deprecated. Use `$GITHUB_OUTPUT` env file

To avoid untrusted logged data to use `save-state` and `set-output` workflow commands without the intention of the workflow author we have introduced a new set of environment files to manage state and output.

Starting 1st June 2023 workflows using `save-state` or `set-output` commands via stdout will fail with an error.
