Remove required Snyk workflow from pull requests

[kyleecodes]

Overview

We need to remove the security/snyk (chaynteam) workflow that is required in YSM's pull requests because we switched to Dependabot and Snyk no longer has access to Chayn's GitHub. This will involve some research as I am not sure where the workflow is coming from -- strangely I cannot find it in our workflow code or in the GitHub Actions settings. Snyk has been disabled as an authorized GitHub app in both organizational and repo GitHub settings, and pull requests made after have still required the workflow run.

Action Items

Here are some starting points for disabling this workflow...

• Check if GitHub Action cache needs refreshed.
• Check settings in the internal Snyk dashboard which initiated this workflow.

Solution: It's just a branch protection rule, easily removed in settings.
