[docs] [issue43777] Remove description of "pip search" command from tutorial

Bob Kline <bkline@rksystems.com> added the comment: Thanks for the clarification. I submitted a PR, but I'm unable to remove the "CLA not signed" tag from it (even though I have signed the CLA) and form at https://check-python-cla.herokuapp.com/ ("You can check yourself to see if the CLA has been received.") blows up with a 500 ("Server got itself in trouble"). Submitting patches for the Python documentation never used to be this hard. :-) ---------- _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue43777> _______________________________________
