tsserver is deprecated, use ts_ls instead. Feature will be removed in lspconfig 0.2.0

So, I tried to change tsserver to ts_ls in the mason.lua file, but I got this message when I try to run nvim: [mason-lspconfig.nvim] Server "ts_ls" is not a valid entry in ensure_installed. Make su
re to only provide lspconfig server names.

Here's the change you need to make:
Go to the following path:
~/.config/nvim/lua/josean/plugins/lsp/lspconfig.lua

And then modify the original code which looks like this:

mason_lspconfig.setup_handlers({
  -- default handler for installed servers
  function(server_name)
    lspconfig[server_name].setup({
      capabilities = capabilities,
    })
  end,
...

To this:

mason_lspconfig.setup_handlers({
  -- default handler for installed servers
  function(server_name)
    -- https://github.com/neovim/nvim-lspconfig/pull/3232#issuecomment-2331025714
    if server_name == "tsserver" then
      server_name = "ts_ls"
    end
    local capabilities = require("cmp_nvim_lsp").default_capabilities()
    require("lspconfig")[server_name].setup({
      capabilities = capabilities,
    })

    lspconfig[server_name].setup({
      capabilities = capabilities,
    })
  end,
...

And then open nvim and do the following:
:Lazy reload mason.nvim mason-lspconfig.nvim mason-tool-installer.nvim

Thank you so much man, it works!

For those who come later, the remapping from mason-lspconfig to ts_ls is now complete.
