License in Base64

[nigate]

Describe the issue
Information is incomplete for base64 license key

The part of the documentation that requires updating
https://docs.arcion.io/docs/arcion-on-premises-ui/okta/
This line
ARCION_LICENSE specifies the base64 encoded Replicant license.

Should also state that the entire license file needs to be converted to make it clear it's not just the key that needs to be encoded.
