Doc links take nowhere #128

I got a hint printed when running a lightning.Trainer object, which sent me to the PyPi page for litModels. There is a link to documentation there which points to the non-existing https://lightning-ai.github.io/litModels/

Coming to the repo here in GitHub, the "Docs" link in the readme points at
https://lightning.ai/docs/overview/model-registry

which also doesn't seem to exist, and redirects to the "getting started" documentation for pytorch lightning.

I find it very bad manners to use one product to advertise another, and I find it particularly annoying when said advertised product is not even properly documented. Please set a proper documentation place for this project, or otherwise stop plugging it into other projects until there is a reasonable way of reading what the suggestion is about.
