Adding a new token guide

[cpungasc]

Hello!

Checked adding a new token wiki section and got a bit confused by the last sentence:

That should be all that is needed to create a new token.

Unless I am wrong about how canarytokens works, it is also necessary to make adjustments to the frontend (ex: generate_new.html, optionally add an icon etc.). If that's true, then the last sentence on the wiki may create false expectations for some people.

Thank you!
