chore(workflows): Remove usage of deprecated set-output command

This is necessary because Github will eventually remove this deprecated command:
https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/
It replaced the `r0adkll/sign-android-release` github action that signs the APK
by `ilharp/sign-android-release` because this alternative version already fixed
the warnings from these deprecated commands in:
ilharp/sign-android-release#10
While the `r0adkll/sign-android-release` still haven't addressed this issue:
r0adkll/sign-android-release#80
