Error setting up OTBR ''extra spaces found"

I tried to install openthread/OTBR as mentioned on the official website.

Here is the output

```
# podman run --sysctl "net.ipv6.conf.all.disable_ipv6=0 net.ipv4.conf.all.forwarding=1 net.ipv6.conf.all.forwarding=1" -p 8080:80 --dns=127.0.0.1 -it --volume /dev/ttyUSB0:/dev/ttyUSB0 --privileged docker.io/openthread/otbr --radio-url spinel+hdlc+uart:///dev/ttyUSB0
Error: 'net.ipv6.conf.all.disable_ipv6=0 net.ipv4.conf.all.forwarding=1 net.ipv6.conf.all.forwarding=1' is invalid, extra spaces found
```

please try to reproduce the bug in latest devel branch

unable to do so.

**Expected behavior**

**Actual behavior**
