fixes https://github.com/FirebaseExtended/action-hosting-deploy/issues/247

This updates the "@actions/core" package to fix the deprecated setOutput warning per Github's instructions.

This warning appears as an annotation when run:

Important info on deprecation dates from Github:

We are monitoring telemetry for the usage of these commands and plan to fully disable them on 31st May 2023. Starting 1st June 2023 workflows using save-state or set-output commands via stdout will fail with an error.

NOTE: June 1st, 2023 is when this action will start failing with an error unless fixed.

I'm getting the CLA sorted. Unless you want me to close this and just upgrade on your end?

@f0urfingeredfish any luck on the CLA Nick? 😟

[f0urfingeredfish]

@NKalganov I have had no luck. I have signed the CLA and so had my company and when I go to have it check again Google gives me a 400 error on this PR CLA check

Re-opening to see if CLA check gets triggered again

Closing in favor of this PR https://github.com/FirebaseExtended/action-hosting-deploy/pull/279 which includes the same fix and the author has a working CLA check.

I also discovered that you can't just upgrade the @actions/core package you also need to upgrade microbundle because there is a bug in microbundle (parcel) that doesn't bundle the crypto package correctly and you will get this error Error: crypto.getRandomValues() not supported. See https://github.com/uuidjs/uuid#getrandomvalues-not-supported when running the workflow.
