2. Fill out the following pre-review checklist:

   • I am adding a new automated test(s) to verify correctness of my new code
   • I am adding new logging messages
   • I am adding a new telemetry message
   • I am modifying authorization mechanisms
   • I am adding new credentials
   • I am modifying OCSP code
   • I am adding a new dependency

3. Please describe how your code solves the related issue.

   Remove the upper bounds in check_compatibility() and keep only the minimum-supported-version checks:

   • chardet: >= 3.0.2 (was >= 3.0.2, < 6.0.0)
   • charset_normalizer: >= 2.0.0 (was >= 2.0.0, < 4.0.0)

   Dropping the upper bound avoids re-introducing this warning every time a new major version of either dependency is released, as recommended in https://iscinumpy.dev/post/bound-version-constraints/. Imho this is the correct way as this produces false alarms on perfectly working setups which trains people to ignore the warning entirely... Arguably worse than no check. Also the bound never actually protects against anything because chardet/charset_normalizer are already imported before the check runs. So even with breaking API change, the connector would break wether the warning fired or not.

   Verified check_compatibility() in isolation.
