[request] export the legacy token program address in the js client

[nickfrosty]

can we add the legacy token program address as an exported constant to the codama generated js client?

Reasoning

since the @solana-program/token-2022 is backwards compatible with the legacy token program client, if the token22 client exported the legacy token program address: developers could easily utilize this single package. manually utilizing the programId arguments with the legacy token program id.

Makes sense to me! What do you think @lorisleiva ?
