Update social networks in the footer

[thibaudcolas]

Currently we list GitHub, Twitter, YouTube in the footer. Instead I think we should have LinkedIn, GitHub, YouTube, Mastodon, Bluesky? Not sure about the order. cc @vossisboss @cnk

I agree with that @thibaudcolas. As for order, I say let's put them in whatever order the logos and links look nicest in.

GitHub and YouTube are in the footer currently. URLs for other options:

• https://bsky.app/profile/wagtail.org
• https://fosstodon.org/@wagtail
• https://www.linkedin.com/company/wagtail-cms/

@cnk I would like to take this issue

@suvanbanerjee We don't assign issues but would be happy for you work on it.

Based on where I see references to the current social media icons, you will probably want to explore setting up the Django Pattern Library and then make modifications to the templates you see there. https://github.com/wagtail/wagtail.org/blob/4d670cea7fc8296cf9a92558d7a0583bdc0df5c7/docs/frontend/general-info.md
