`generateP256KeyPair` does not work on NodeJS 18

[BriungRi]

Get this error:

crypto.getRandomValues is not a function

Upgrading to NodeJS 20 fixes

[r-n-o]

@BriungRi that's strange, I see in the documentation that crypto.getRandomValues was added in v15:

Locally I also checked that v18 includes this function:

❯ node
Welcome to Node.js v18.18.2.
Type ".help" for more information.
> let r = new Uint8Array(32); crypto.getRandomValues(r)
