v0.10.8 Fixed auto-comple for VSCode+Polyglot

• Added a replace directive from go.lsp.dev/{jsonrpc2,uri,protocol} to github.com/go-language-server/{jsonrpc2,uri,protocol}
  in go.mod, since go.lsp.dev seems to be down.
• Updated dependencies to go.lsp.dev/uri and go.lsp.dev/protocol.
• Set MIMEType KernelLanguageInfo.MIMEType, which enabled auto-complete with VSCode+Polyglot to work with GoNB+Auto-complete.
  Thanks @tonidy for the find and fix. More in dotnet/interactive#3511
• Updated Dockerfile to build the docker from main/HEAD.
