Update Enterprise badge applies to SAML as well

What does this MR do?

This Docs MR is a small modification to when Enterprise badge gets applied to users - to be for both SAML and SCIM provisioned users.

As part of the Enterprise Users epic, the MR writes Adds an "Enterprise" badge to group members that were provisioned via SAML/SCIM., but in the current docs, only SCIM provisioning gets the Enterprise badge.

I think this is the relevant section in the code:

• To check whether a user is provisioned by group: https://gitlab.com/gitlab-org/gitlab/-/blob/v14.8.2-ee/ee/app/models/ee/group_member.rb#L37
• Show enterprise badge: https://gitlab.com/gitlab-org/gitlab/-/blob/v14.8.2-ee/ee/app/assets/javascripts/members/utils.js#L36

A customer (internal ZD ticket) with no SCIM setup has users with Enterprise badge next to some users.

Author's checklist

• Consider taking the GitLab Technical Writing Fundamentals course.
• Follow the:
  • Documentation process.
  • Documentation guidelines.
  • Style Guide.
• Ensure that the product tier badge is added to topic's h1.
• Request a review based on:
  • The documentation page's metadata.
  • The associated Technical Writer.

If you are only adding documentation, do not add any of the following labels:

• ~"frontend"
• ~"backend"
• ~"type::bug"
• ~"database"

These labels cause the MR to be added to code verification QA issues.

Review checklist

Documentation-related MRs should be reviewed by a Technical Writer for a non-blocking review, based on Documentation Guidelines and the Style Guide.

• If the content requires it, ensure the information is reviewed by a subject matter expert.
• Technical writer review items:
  • Ensure docs metadata is present and up-to-date.
  • Ensure the appropriate labels are added to this MR.
  • If relevant to this MR, ensure content topic type principles are in use, including:
    • The headings should be something you'd do a Google search for. Instead of Default behavior, say something like Default behavior when you close an issue.
    • The headings (other than the page title) should be active. Instead of Configuring GDK, say something like Configure GDK.
    • Any task steps should be written as a numbered list.
    • If the content still needs to be edited for topic types, you can create a follow-up issue with the docs-technical-debt label.
• Review by assigned maintainer, who can always request/require the reviews above. Maintainer's review can occur before or after a technical writer review.
• Ensure a release milestone is set.
