Emulator storage limit doesn't match production limit

### [REQUIRED] Environment info

**firebase-tools: 13.15.4**

**Platform: MacOS**

### [REQUIRED] Test case

`npx firebase-tools emulators:start`

### [REQUIRED] Steps to reproduce

1. Load the storage UI from a clean install of Firebase Tools
2. Upload an image larger than 150MB
3. Observe `PayloadTooLargeError: request entity too large` error

### [REQUIRED] Expected behavior

I expect that the file size limit of the emulator to be equal to what the limit is in production.

### [REQUIRED] Actual behavior

The limit is set to 136314880 bytes (~136MB) in the emulators (found by working back from the error, not by finding where it's explicitly set) whereas I believe the actual limit in Firebase is [5 TiB](https://cloud.google.com/storage/docs/uploads-downloads)
