Remove link to facebook and add LinkedIn in the Python.org socialize menu

[riecatnor]

Along the same lines as issue #2322 I would suggest making two more small changes to the Socialize menu:

• Remove the Facebook link, the last post being almost 10 years ago (March 2014) it is effectively dormant and doesn't make sense to send folks there, imo.
• Add a link to the PSF LinkedIn page, which is active and has a significant following (127k followers).

Feel up for doing some more icon magic?

Yeah, definitely! Happy to help. I'll find some time to work on this.

could you assign me this issue?

[hugovk]

@sahanasurapureddy No, we usually don't assign issues because sometimes people disappear and then the next person doesn't know if they're still working on it or not.

And in this case, see the message directly above yours: someone else is planning on doing this. Let's give them a chance first. Thanks!

#2327 was superseded by #2367 which has been merged.
