Optional userstore "Display Name" marked as mandatory

[janakamarasena]

Describe the issue:
When creating a user store under "User" config there is a mandatory attribute names Display Name. When checking the carbon management console this is an optional attribute. Furthermore having this as a mandatory attribute hinders the UX as its not intuitive what this attribute is for. The old carbon console has the following info against the attribute
"This is the attribute name to display as the display name of the user"

Expected behavior:
Display name should not be mandatory

DisplayNameAttribute required property is coming as true

The mandatory check was removed with: wso2/identity-apps#5282

Additionally, the placeholders of these fields are dynamically generated and doesn't make much sense.

Ex: Display Name here is meant for the attribute used for the displayname property of a user in the userstore. But that's not intuitive in the UI.

We need to revamp the placeholders and possibly add hints:

Since we dynamically populate this UI based on the API response, shouldn't this be fixed from the BE as well?
