Social media links on https://pycon.org/

[Gailogail]

Currently conferences on this page have a "Follow on Twitter" link. Can we have (or if one exists, can you point me to) a mechanism to link to other social media platforms. This could be in addition to or instead of the Twitter link. I guess the Twitter one ought now to be X.

PyCon UK has a presence on BlueSky, LinkedIn, Mastodon and X.

To implement this, we could just expand on the current Twitter optional link: https://github.com/PyCon/pycon.org/blob/gh-pages/index.html#L139

And ensure any added values are detailed on the README.
