[Feature Flags] Show tags in audit log tables

[michellewzhang]

The audit log item contains tags that might be useful to display alongside the info we already show (created at, provider name, etc.)

Two spots:

• feature flag settings page
• issue details tags/flags drawer > feature flag details

Failed to route for Product Area: Feature Flags. Defaulting to @getsentry/dev-infra for triage ⏲️
