Add More API Routes to Client

[bh2smith]

This generated sdk is cool, but it only includes the SwapApi.

Would be good to extend it beyond (E.g. https://dev.jup.ag/docs/token-api/v2)

Here is a sample PR, following the same flow for the TokenApi

using the following swagger.yaml file:

https://raw.githubusercontent.com/bh2smith/jupiter-agent/f002ead3096abd29ca91b002eb9a9aa53ac0ad2f/token.swagger.yaml

slightly modified from the docs source: https://github.com/jup-ag/docs/blob/main/openapi/token.v2.yaml
