Thanks for doing this. We should also make sure to add a Yarn constraint in constraints.pro that enforces that all packages have a changelog:update package script. You should be able to copy the existing one for changelog:validate here: https://github.com/MetaMask/core/blob/main/constraints.pro#L269

Constraint added, but actually both they only check if it's valid no error is thrown if it doesn't exist

Oh! Hmm. Alright, I guess we can fix that issue in another PR.

One fix needed, but this is otherwise good to go!
