Update "Share" output content for better UX and user engagement

[BrandonML]

Attached is how the share function currently works with WhatsApp. It does the job, but could be improved.

• Generate different versions of the content for channels that are text based and don't allow styling like Whatsapp, and those that do, like some SM channels, email, etc.
• Give more spacing between the two links for better separation.
• Move the Tabby extension link to the bottom, giving more attention to the cat's actual profile link.
• Are short links a valid and useful idea to replace the long links we currently show?
• Ideally, the cat photo should be the primary focal point, so, whenever possible, it should come before the adoption details text.
