User Auth Token not showing

### Environment

self-hosted (https://develop.sentry.dev/self-hosted/)

### Steps to Reproduce

1. Open UI screen to generate User Auth token
2. Set any permission option
3. Generate token

### Expected Result

Token is created and shown in the UI for the user to copy

### Actual Result

UI times out waiting on the fetch request, and simply does nothing apart from drop the loader spinner.
Token is created in the backend and visible in the list however it can not be seen or copied.

### Product Area

Settings - Auth

### Link

### DSN

### Version

24.1.0

Start in the Settings - Auth UI and reproduce the token-generation flow with a permission selected. Trace the fetch request that times out after the backend creates the token. Done means the generated token is shown in the UI for the user to copy, without the loader being left behind.
