Enable Snyk Test Workflow in GitHub Actions

[simonhkhan]

Overview

• Runs Snyk tests when any commits are pushed to branches develop, release/**, feature/**, master, main

Updates

• Adds github action step to install Snyk CLI to run the snyk test command. This was done since running the Snyk CLI commands will leverage the JAVA environment that was already built in previous steps.
• Adds github action step to run the Snyk test using the CLI command. Adds a 90 second timeout in case the CLI test scan hangs.
• Updates gradle build step to disable the cache since a network issue was preventing access to the cache which failed the build step. The build step takes ~10 seconds with the cache disabled.
