Remove Tagless doc. link from menu

• Remove the link to Tagless from the docs sidebar menu, as the information related to it, it is now integrated in other sections, per this PR: Equality for tagless and update Quick Start #488

Apart from that, IMHO, we should create a redirect from /docs/core/tagless to the new path in order to redirect the users whose find this old path in google.

What do you think?

That would be great, but I doubt we can do it as I think that the info is now spread apart between different sections in the documentation, I could be wrong though.
