Issue:
Unable to use evniroment to set internal authentication user and password
### Which version are you using?

v1.15.3

### Which operating system are you using?

Linux amd64 Docker

### Describe the issue

Hello,

I'm trying to setup a public test RTSP server which I can use as a RTSP source.
I've managed to use FFmpeg to push video to the server and now I want to make it secure and prevent others from pushing video to the server while making anyone able to read from it.
I've decided to use an env variable to set user and password to hopefully avoid commiting them, but while in `runOnInit` the parameters get replaced correctly, the `user` and `pass` fields won't. If I replace `${RTSP_STREAMER_USER}` and `${RTSP_STREAMER_PASS}` (on in the auth config) with the actual values it will work, so it's not an issue of the environment variables getting read.

Any help? Thx

Rico

### Describe how to replicate the issue

1. Set config as provided
2. Set `RTSP_STREAMER_USER` and `RTSP_STREAMER_PASS` environment variables (I'm using a `.env` file and importing it with docker compose)
3. Provide any random video file to test and edit the config accordingly
4. Start mediamtx
5. Check logs for errors

### MediaMTX configuration
```yml
# mediamtx.yml

```

+   Parameters in lists can be overridden in the same way as parameters in maps, using their position like an additional key. This is particularly useful if you want to use internal users but define credentials through enviroment variables:
