Update permissions-required-for-github-apps.md

[mcfluffinstein]

Adjusting permissions after feedback on https://github.com/github/external-identities/issues/2534.

Why:

It's not possible for GitHub Apps to access these endpoints without write permissions. This is a known bug with querying SAML/SCIM identities with Read only permissions for members. https://github.com/github/external-identities/issues/2534. We won't have a bug fix for this out any time soon, so the engineering team responsible for it asked if I could raise a docs PR.

What's being changed (if available, include any code snippets, screenshots, or gifs):

I'm updating the permissions required for GitHub Apps to access GET /scim/v2/orgs/:org/Users and GET /scim/v2/orgs/:org/Users/:external_identity_guid. Both of these endpoints require Members write permissions as highlighted on the issue.

- [`GET /scim/v2/orgs/:org/Users`](/rest/reference/scim#list-scim-provisioned-identities) (:read)
+ [`GET /scim/v2/orgs/:org/Users`](/rest/reference/scim#list-scim-provisioned-identities) (:write)

and

- [`GET /scim/v2/orgs/:org/Users/:external_identity_guid`](/rest/reference/scim#get-scim-provisioning-information-for-a-user) (:read)
+ [`GET /scim/v2/orgs/:org/Users/:external_identity_guid`](/rest/reference/scim#get-scim-provisioning-information-for-a-user) (:write)
