Add Wallet Tag

[Centenoe]

A common question a lot of people have when starting to use the Tezos ecosystem is "what wallet should I use?" having a wallet tag would be very useful! I would be more than happy to add the Tezos supported wallets such as Temple, AirGap, Kukai, etc.

Would you consider having the actual tezos.com/ecosystem page open source? I could add that category and add supported links such as GitHub, Discord etc.
