Support disabling rates limit

### Describe the problem

This is my current rate limits configure
```yaml
rates_limit:
api:
window: 10 seconds
max: 0
login:
window: 5 minutes
max: 0
signup:
window: 5 minutes
max: 0
ask_send_email:
window: 5 minutes
max: 0
receive_client_log:
window: 10 minutes
max: 0
plugins:
window: 10 seconds
max: 0
well_known:
window: 10 seconds
max: 0
feeds:
window: 10 seconds
max: 0
activity_pub:
window: 10 seconds
max: 0
client:
window: 10 seconds
max: 0
```
When I visit the page, I received `429 Too many request` error.

If I want to set all peertube rate limits to unlimit in v6.0.1, what value should I set?

### Additional information

* PeerTube instance URL:
* PeerTube version: v6.0.1
* NodeJS version: v18.19.0
* Ffmpeg version:
* Redis version: 7.0
* PostgreSQL version: 13.3

Start by tracing the rates_limit configuration entry point for max: 0 and reproduce the 429 behavior described for PeerTube v6.0.1. Check how the listed rate-limit groups interpret an unlimited setting, then verify that requests no longer receive 429 responses when limits are disabled.
