[docs]: example shows use of chpasswd which was deprecated in cloud-init 22.2

[brianandrus]

Documentation request

When trying to use the examples at https://docs.cloud-init.io/en/latest/reference/yaml_examples/set_passwords.html I get:
Deprecated cloud-config provided: chpasswd.list: Depcrecated in version 22.2. Use users instead.

I suspect the documentation needs updated.

Reported from: https://docs.cloud-init.io/en/latest/reference/yaml_examples/set_passwords.html
