[DOCS] http -> https, remove outdated plugin docs (#60380)

Plugin discovery documentation contained information about installing

While noticing that the instructions used cleartext HTTP to install
packages, this commit replaces HTTPs links instead of HTTP where possible.

In addition a few community links have been removed, as they do not seem
to exist anymore.
