Should add documentations from language server in terminal suggest completion item.
For example, users using Python REPL with terminal suggest should have not only the completions items from LSP show up, but also their documentation method usage as they would normally see inside Python file in editor.

Try to figure out how we can get documentation info when inside provideCompletions method in file src/vs/workbench/contrib/terminalContrib/suggest/browser/lspCompletionProviderAddon.ts
