Discriminator is not implemented for anchor_spl: :token_interface::Mint and anchor_spl::token_interface::TokenAccount

[cxp-13]

I'm following a tutorial https://www.soldev.app/course/token-extensions-on-chain, github: https://github.com/Unboxed-Software/token22-staking

My dependency situation is

[dependencies]
anchor-lang = "0.30.1"
anchor-spl = "0.30.1"
solana-program = "2.0.4"
spl-token = "6.0.0"
spl-token-2022 = "3.0.4"

When I try to use the token_interface module in anchor_spl, after executing anchor build I get the trait Discriminator is not implemented for anchor_spl: :token_interface::Mint and anchor_spl::token_interface::TokenAccount.

Please see answer #2745 (comment).

There is also going to be a warning for this in the next version (#3133).
