Nice, LGTM with additional notes to skip server 9.0.0+ and require libmongocrypt 1.18.1.

Also note: "Skip this test case if testing MongoDB server 9.0.0+." note (similar to Case 7) to cases 8 and 9 (requiring prefixPreview and suffixPreview).
And note that libmongocrypt 1.18.1 is required for test cases 8 and 9 since those are regression tests for MONGOCRYPT-903.

Background
Tests case and diacritic insensitivity. Also serves as a regression test for MONGOCRYPT-903. Note: the fix was released in libmongocrypt 1.18.1
Test implementation
Unlike other text prose tests, the new case and diacritic tests use automatic encryption to insert the test document. This is because the libmongocrypt bug reversed case and diacritic sensitivity both on the insert and find, causing the tests to pass.
