specify what you mean by language server configuration

you say in the documentation:

Server capabilities are defined in capabilities.R. Users could override the capabilities by specifying the LSP configuration setting server_capabilities or options(languageserver.server_capabilities) in .Rprofile. For example, to turn off definitionProvider, one could either use LSP configuration

"r": {
    "lsp": {
        "server_capabilities": {
            "definitionProvider": false
        }
    }
}

or R options

options(
    languageserver.server_capabilities = list(
        definitionProvider = FALSE
    )

someone who knows R should be able to figure out that the R options can go into the .Rprofile but I am not sure what file this JSON example refers to, or where to put it; it would be nice if context was added for newcomers to LSP (like me);especially people coming from RStudio where we don't have to think about LSP. You could say 'LSP configuration via this file located at such and such location in linux/mac and such and such location in windows`. That would be helpful.

Start by locating the documentation passage that references capabilities.R and the .Rprofile option. Identify and document where the JSON-based LSP configuration belongs on Linux, macOS, and Windows, adding enough context for users unfamiliar with LSP; the examples should make both configuration methods unambiguous.
