replace twitter with hackyderm

[drmowinckels]

in our social media bits (that display in the footer for instance) we need to change twitter with hackyderm.

href="https://hachyderm.io/@RLadiesGlobal"

I believe the social media functions in hugo that I made should be able to handle this as long as its correct in the config.
What is important though, is that we get the mastodon rel="me" html tag in there, so we can display ourselves as verified on hackyderm.

@cosimameyer you have some experience with mastodon. Want to take a shot?

[cosimameyer]

Absolutely! I'll give it a try tomorrow 🥳

[cosimameyer]

Just to confirm: We want to add our Mastodon handles to the website and remove the Twitter handles, right? Here's the PR that I set up: #217

(it also includes the verification for the Mastodon account)

I just wasn't sure what to do with the We are R-Ladies and IWD R-Ladies accounts and whether the Twitter account should be fully removed (just de-activated the footer relink for now)

[yabellini]

For the IWD it is ok to de-activate the link. We don’t have a new account for that one, but I think we should only create one if we are going to do campaigns.

PRs are merged ✅
