Refer to official docs

Currently, I is not clear if this README is the best and updated source for documentation for TerminalMenus. To me, it would feel more appropriate to replace the readme with a short description of the history and scope of the package, and then just link to the official docs.

Would you agree? Because the current situation feels like it is split between this package and the official docs, and the maintenance burden is doubled (right)?

In fact, if the code in this repo is not what ships with julia by default, then that should be stated explicitly. Perhaps something like "thos project has moved to (link to the julia repo folder for terminalMenus). The docs are available at (link to docs). And that could be the entire readme.

Perhaps with a little more of the flair and joy over having this in the stdlib, which is currently present ^_^
