docs: inconsistency in documenting behavior of reload vault config

https://www.nomadproject.io/docs/configuration#configuration-reload

> note this only reloads the TLS configuration between Nomad and Vault, but not other configuration values

https://www.nomadproject.io/docs/configuration/vault#vault-configuration-reloads

> The Vault configuration can be reloaded on servers. This can be useful if a new token needs to be given to the servers without having to restart them

Not sure which one is the expected behavior (clearly the second one would be much preferable), so could you help to verify and correct the documentation?

Start with the two linked Nomad documentation sections and compare their descriptions of Vault configuration reloads. Verify the actual behavior before deciding which statement is correct, then update the documentation so both sections describe it consistently.
