docs(example): remove import entries as they confuse new users

[dpetka2001]

Fixes LazyVim/LazyVim#5854. Would be good to not mention import entries in example.lua, so that the LazyVim website docs don't mention them as they confuse new users, especially with the new warning about "wrong order".

Thanks so much for creating a PR. I think these plugins are very useful, and I have been using them, so perhaps a future state in the documentation might suggest where is an appropriate place to put these imports?

There was a mention in the past, but like I said it got removed because new users were confused and that lead to issues. See #75. Users should just use the command :LazyExtras to avoid any such issues like yours. As they get accustomed to how things work in Lazyvim and lazy.nvim they will discover this feature and judge if they want to use it or not. I don't believe a future mention is necessary in my personal opinion, as it will only have the same effect as if these lines were not removed.

Actually my PR is same as #52, but I'll leave it open, so that maintainer maybe notices it again and merges #52 instead of mine.
