Is your feature request related to a problem? Please describe.

I noticed the docs specify the query port as an optional Integer, but the binary expects a String instead:

[query]
Docs: port = 12345
Default toml: address = "0.0.0.0:25565"

Describe the solution you'd like

Update the query config docs to list address as a string value, matching the latest default configuration.
