Update all account create examples to use an ECDSA public key and set the corresponding EVM address derived from it

[SimiHunjan]

Problem

To reduce confusion about the key type to use when creating accounts, we need to update all examples to use ECDSA public keys and set the corresponding EVM address

Solution

• Review all places where the docs show how to create an account
• Update all places to demonstrate the following:

const transaction = new AccountCreateTransaction()
     .setKey(ecdsaPublicKey)
     .setAlias(ecdsaPublicKey.toEvmAddress())
     .setInitialBalance(new Hbar(1))
