Missing information in connect to an oidc provider documentation

[maryarm]

Description

On the docs page, there are some missing information regarding environment variables and considerations:

1. The SPRING_PROFILES_ACTIVE=oidc is missed from Environment variables tab.
2. The fact that IDENTITY_INITIAL_CLAIM_NAME and IDENTITY_INITIAL_CLAIM_VALUE env variables are only applied once in during startup of identity only when there is no mapping rule in mapping_rules table and the changes are not effective afterward, is missed from documentation and can confuse customers.

Possible solution

The documentation should be updated to correctly reflect these two item.

Added this to the DevEx board - @conceptualshark is this something you can take a stab at and add Maryam as a reviewer?

👍 Can do - I have some open work on this page, and this should fit right in.
