docs: add lua to runtime path

[mikesmithgh]

👋 hey! I think I found a typo in the configuration instructions.

Using plenary.nvim as an example, when I have

library = vim.api.nvim_get_runtime_file('', true),

it includes the path /Users/mike/.local/share/nvim/lazy/plenary.nvim which lua_ls does not seem to pickup on the child lua directory.

Changing it to

library = vim.api.nvim_get_runtime_file('lua', true),

it includes the path /Users/mike/.local/share/nvim/lazy/plenary.nvim/lua and everything works as expected. lua_ls picks up on the plenary plugins functions it, describe, etc.

Please let me know if you need any other info.

Do not change server_configurations.md directly. Edit the lua source file instead. See https://github.com/neovim/nvim-lspconfig/blob/master/CONTRIBUTING.md#generating-docs

this is not correct

@glepnir Hey yep you are right. This turned out to be a misconfig on my side.

I had: (note the extra curly braces)

                {
                  workspace = {
                    checkThirdParty = false,
                    -- Make the server aware of Neovim runtime files
                    library = vim.api.nvim_get_runtime_file('', true),
                  },
                },

I remove those and now it works perfectly fine.

                workspace = {
                  checkThirdParty = false,
                  -- Make the server aware of Neovim runtime files
                  library = vim.api.nvim_get_runtime_file('', true),
                },

well... sometimes you have to go down the rabbit hole to find a couple of rogue curly braces I guess 😂. Feel free to close.
