vim-lsp supported

[albfan]

While README.md claims vim-lsp is not supported:

Note: This tool is not compatible with vim-lsp as it only supports LSPv2.0.

https://github.com/georgewfraser/java-language-server/blame/master/README.md

vim-lsp-settings include java-language-server as a ls for java

Probaly this is just an outdated note (it is 3 years old now)

Any doc about lsp 2.0 vs lsp 3.0? I just found https://github.com/microsoft/language-server-protocol/blob/main/versions/protocol-2-x.md but unsure what is the different.

I can create a PR removing that if there's no more info
