* "Liquid Staking" Page Update (#709)

* Update _generate_validator_keys_wagyu.md (#710)

Adding a warning about entering a withdrawal address at the key generation step in Wagyu. This idea comes after seeing multiple validators not paying attention to it recently and ending up having to update their withdrawal credential using Ethdo after which is not really easy for non technical people. This warning should hopefully prevent such cases in the future.

* Update voluntary-exit.md (#711)

Fixing a warning that wasn't really exact, as updating a 0x00 withdrawal credential is also possible on an exited validator as well but is much more challenging because the node is most often offline.
