We currently test that FLE works with multitenancy by using the encrypted shell in ...enterprise/jstests/serverless/native_tenant_data_isolation_simple_FLE2_dollar_test.js. Once we start doing validation checking when constructing NamespaceStrings, the encrypted shell will fail commands with $tenant on them, because they will attempt to construct NamespaceStrings using the tenantId in $tenant, but the encrypted shell will not have multitenancySupport enabled. This test is being disabled in SERVER-73112, and in this ticket we should re-enable this test.
