Better documentation for MCP Client properties

[kdubois]

Related to #1249 I was trying to get an example MCP sse server + client up and running but it was pretty hard to figure out how to configure the app because I couldn't find an exhaustive list of MCP client properties on https://docs.quarkiverse.io/quarkus-langchain4j/dev/mcp.html . Can we add a bit more documentation on how to use it and add a list of config properties ?

Ah, we could add a configuration reference like we have in other parts of the doc, right. That would be a good start.

Note that I don't intend to duplicate too much stuff from the langchain4j documentation (https://docs.langchain4j.dev/tutorials/mcp/) so that's why the quarkus documentation contains a link to that one, the user may have to look there too.

Ok yeah that makes sense, that way there's less risk of things getting outdated vs the langchain4j docs. As long as the quarkus docs have the config reference
