Github Actions Remove --max-workers gradle param (#1444)

Motivation:
Our github action scripts explicitly set --max-workers but gradle can
automatically infer the value based upon number of processors [1].

[1] https://docs.gradle.org/current/userguide/command_line_interface.html
> Default is number of processors.

Modifications:
- Remove --max-workers param from github action scripts

Result:
Gradle will automatically determine the number of workers to use based
upon available processors.
