[Tooling] - genkit start won't attach to Firebase Emulator Suite

[codercatdev]

Describe the bug Trying to run genkit start -- firebase emulators:start --inspect-functions doesn't attach to firebase emulators. This seemed related to #590 but there is no --attach command available in this version.

Emulators run and genkit ui runs, but it doesn't connect.

Running into the same issue.

Also, would be helpful if the genkit ui was on a different port as it conflicts with the emulator port 4000 (or vise versa). This addresses the port conflict, but the problem persists:

genkit start --port 4001 -- firebase emulators:start --inspect-functions
