Updates social icons

[Shrinks99]

One more PR that would have made finding this easier for me :)

Changes

• Adds a social link to Bluesky
• Adds a social link to GitHub
• Adds rel="me" to all SUCHO social links to identify them as yours! This will act as verification on Mastodon.
  • You'll have to update your link in the Mastodon settings for that to appear, just remove and re-add it!
• Adds a link to ReplayWeb.page where the URL was already available in text
• Updates Mastodon hover color to their new branding
• Updates FontAwesome

Caveats

If you update your Bluesky handle to use your domain name (Which also acts as verification on there, and enables you to move your account later!) you'll need to update the link here. Best to do that sooner rather than later because of link breakage!
