[doc] generatePrivateKey takes 1 parameter

[dagurval]

The documentation wrongly states it takes secp256k1 as first parameter: https://github.com/bitauth/libauth/blob/071f9cdd/src/lib/key/key-utils.ts#L70

Thanks for opening an issue! Yes, that tsdoc line seems to be outdated now. Would you mind sending a PR to remove it? (I can definitely remove that line in the next release, but I'd love to merge a PR to credit you as a contributor.)
