Replace action-read-yaml with $GITHUB_ENV in GitHub actions

The Java configuration (e.g. version) is exteranlised to a properties file, which is YAML parsed via a third-party action.

[It was identified](hazelcast/hazelcast-packaging#204 (comment)) that this operation was possible without using a third-party action using `$GITHUB_ENV`.

For consistency, everywhere should use the same parsing logic.
