patch 9.0.1790: Redundant LSP Content-Type header
Problem: The Content-Type header is an optional header that some LSP
servers struggle with and may crash when encountering it.
Solution: Drop the Content-Type header from all messages, because we use
the default value anyway.
Because pretty much all popular LSP clients (e.g. coc.nvim, VSCode) do
not send the Content-Type header, the LSP server ecosystem has developed
such that some LSP servers may even crash when encountering it.
To improve compatibility with these misbehaving LSP servers, we drop
this header as well.
