chore: add missing changeset for PR 250

[marandaneto]

💡 Motivation and Context

PR #250 was merged without a changeset, so the PostHog.AspNetCore fix for feature flag enumeration without a Personal API Key was not queued for release.

💚 How did you test it?

• pnpm changeset status --since=main

📝 Checklist

• I reviewed the submitted code.
• I added tests to verify the changes.
• I updated the docs if needed.
• No breaking change or entry added to the changelog.

If releasing new changes

• Ran pnpm changeset to generate a changeset file

🤖 Agent context

Autonomy: Human-driven (agent-assisted)

Pi added a missing changeset for the already-merged fix from #250. The changeset targets PostHog.AspNetCore with a patch bump because the original PR fixed existing feature management behavior without a public API change.
