Wrong secp256k1 point in PublicKey docs

[gilcu3]

Today I was trying to use the example secp256k1 PublicKey from https://docs.rs/near-sdk/latest/near_sdk/struct.PublicKey.html and noticed that it does not belong to the secp256k1 elliptic curve. Example point in https://www.npmjs.com/package/near-sdk-js/v/1.0.0 is correct.

The bug can be tested with something like:
