How to clear handlers to unknown lspconfig servers?

[robertsawko]

After a recent update of Mason, I started receiving a warning like this, when opening C++ files

mason-lspconfig.setup_handlers: Received handler for unknown lspconfig server name: tsserver.

I am suspecting that tsserver is TypeScript standalone server, but I am not too sure? I don't believe I ever installed it myself, but maybe somewhere in my config or some cache files a reference to an old config exists.

I can't find any reference to tsserver in either LspLog or MasonLog. Please let me know.

Seems we need to rename the tsserver to ts_ls based on this change
