## Description
This PR makes the following change to `coder/modules/filebrowser`:
- Use the updated `baseURL` flag instead of the deprecated flag
`baseurl`
Currently upstream [deprecates the `baseurl`
flag](https://github.com/filebrowser/filebrowser/blob/v2.53.0/cmd/root.go#L35-L51)
and prints this into the logs:
```
DEPRECATION NOTICE: Flag --baseurl has been deprecated, use --baseURL instead
```
Also, the upstream sets to [remove the support of the fallback after
July
2026](https://github.com/filebrowser/filebrowser/blob/v2.53.0/cmd/root.go#L56).
Without the fix, it might stop working afterwards.
