[security] audit repository tooling

[EjiroLaurelD]

Hello,
The Security SIG is looking to ensure that security tooling is setup consistently across the organization. As a result, we're asking maintainers to ensure the following tools are enabled in each repository:

• CodeQL enabled via GitHub Actions
• Static code analysis tool (the collector uses govulncheck [https://pkg.go.dev/golang.org/x/vuln] on every build)
• Repository security settings
  • Security Policy ✅
  • Security advisories ✅
  • Private vulnerability reporting ✅
  • Dependabot alerts ✅
  • Code scanning alerts ✅
