feat: ProfilePicture bounce, better tooltip

[ninetailedtori]

ProfilePicture optimisations, make it look pretty AND useful!!!

Direct changes:

• Add a bounce state to the ProfilePicture element
• Also, use a defined "placeholder" class that handles the svg for us, as well as the animations and colours.
  • Move the import from PortMaintainers.svelte to ProfilePicture.svelte to follow this new modular structure.
• Add some optimisations as well
• Add a bespoke tooltip, much more descriptive of the user as well.
• Adds a click state to take you to the maintainer's GH URL. (makes it feel more reactive.)

Related changes:

• Also fixes the fetch for maintainer icons, such that it has a proper retry logic and fail states, as well as updated to match the new profilepicture svelte object.

Unfortunately, I cannot undo index.astro, as the commit hook that runs astro check and fmt actually caused it to end up empty commits every time! Very annoying :(
