Customize listening port for ReactQueryDevtools

[iloveitaly]

Describe the bug

If you have two sites you are working on in parallel, you cannot change the port that <ReactQueryDevtools /> is listening on. This makes it impossible to have two tanstack dev tools running at the same time.

Your minimal, reproducible example

https://github.com/iloveitaly/python-starter-template/blob/e534cf12b01553faee0afac7dbca7659f8c0d59b/web/app/configuration/tanstack-query.tsx#L16

Steps to reproduce

Run the above project in two separate directories: you'll get a port in use behavior.

Expected behavior

Ability to customize the listening & server port when using ReactQueryDevtools (SPA mode for me).
