-- TIP: Setup a new LSP:
-- Step 1: Install the LSP through:
--         OS Installer > Brew-linux > :MasonInstall
-- Step 2: Append the LSP server name in the below array ("newlsp")
-- Step 3: Create file ("newlsp.lua") in ../../lsp/
-- Step 4: Return a lua table containing required lsp config in it
-- NOTE: Only LSPs here, NOT linters or formatter
