### What happened?

I tried to set up my own grid with the help of documentation and command-line help. Some of the examples are not in the correct syntax of a toml file (checked with the linked validator)

### How can we reproduce the issue?

```shell
Check the generated output in the toml validator
```


### Relevant log output

```shell
Unable to parse...
```


### Operating System

Ubuntu

### Selenium version

Java 4.1.1
