If colima's ssh_config is included in an included file, colima still adds another include

### Description

`~/.ssh/config`:
```
Include config.local
# ...
```
`~/.ssh/config.local`:
```
Include /Users/dottedmag/.colima/ssh_config
# ...
```

After running Colima another `Include` is added to the main SSH config file.

Why does it matter? My `~/.ssh/config` is version-controlled and multi-platform. All local configuration goes to `~/.ssh/config.local`, except that Colima puts its include into the main file, even if I manually move it into the local one.

N/A

### Reproduction Steps
