```
docs: Mention required matching configs when developing language server extensions (#38674)

This took me quite a while to find out when I developed my first
language extension. I had non-matching entries in the `languages` array
and in the name field of `config.toml`, and it was especially tricky
because the zed extension would start up, but not the language server. I
sure which this had been in the docs, so I am contributing it now!
