Make brown-slave not one of the valid randomly generated names for a session

Yeouch!

Huh, looking at the list of nouns it looks like slave isn't in there (thank god)

https://github.com/zellij-org/zellij/blob/main/src/sessions.rs#L303

Which is weird, because I'm on v0.37.2.

... huh, it is one of the default words in the names crate but Zellij should be providing its own list.

https://github.com/fnichol/names/blob/main/data/nouns.txt#L770

Maybe I should go file a report on their repo but it is odd that it is using their list instead of the list you pass.

The latest version of names is 0.14.1 and zellij is using 0.14.0 but it looks like it just bumps dependencies.

This has been addressed in #2122. It's in main and will be included in the next release :)
