fix: orcid lowercasing done

[yoganandaness]

Description

In the Visa connector, when creating experiment users, lower the case of orcid and email before saving into the users table

Motivation and Context

During the Visa login, which is using keycloack, the username is being lowercased. However, the username from the user office proposal doesnt. Due to this, the logged in user could not see their corresponding proposals. This can be fixed by lowercasing the username during the acceptance of the proposal
