Enable unity licensing server for macOS

[cseteram]

Changes

GameCI currently supports Unity license server activation, but the Bash scripts for the macOS platform have not been updated to support this functionality. While there was a previous PR addressing this, it has not yet been merged. 😭 This PR revisits and adapts the changes from the previous PR to fit the current Linux-based script structure.

Additionally, since BSD grep (used on macOS runners) does not support Perl-compatible regular expressions, the regex pattern used for license token parsing has been updated to ensure compatibility.

• Added logic to activate and return Unity licenses when the UNITY_LICENSING_SERVER environment variable is set
• Removed the email and password parameters in the build script
• Updated the regular expression pattern for license token parsing to work correctly with BSD grep

Successful Workflow Run Link

I have successfully tested this in our private repository and have attached logs from tests, showing the use of the Unity license server at each step. Since the implementation closely follows the Linux version, I expect it to work without any issues. If necessary, I can provide the full log file of workflows (with secrets masked).

Review skipped

Review was skipped due to path filters

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.

You can disable this status message by setting the reviews.review_status to false in the CodeRabbit configuration file.
