Deprecation of LTS.* packages

[thompson-tomo]

Is your feature request related to a problem? Please describe.
It is not clear on nuget that the LTS.* packages are not being maintained.

Describe the solution you'd like
I would like to see that all the no longer maintained packages are marked as deprecated on nuget.org with a note informing users of the packages they should be using.

Describe alternatives you've considered
Just accept it
