Implementing workspace/configuration

[nangtrongvuon]

Some LSP servers such as the Dart LSP server requests settings with workspace/configuration. Currently there is no way to pass in such settings since helix does not support this yet.

Implementing workspace/configuration (and workspace/didChangeConfiguration) will allow more LSP settings and changing settings on the fly without restarting the server.

I stumbled across this as well while integrating the HTML language server with Helix. I managed to get the language server running, but I couldn't enable formatting as it expects me to set html.format.enable to true. All configuration is done through the Configuration Request.

For the HTML language server specifically, there's a lot of configuration available as can be seen here.
