Subject: [PATCH] fix: pin charset-normalizer to <3 to fix Big5 encoding
 detection (#1628)

charset-normalizer 3.x changed its detection algorithm, causing Big5-encoded
Chinese text to be misdetected as johab (Korean). This breaks the
test_terminal_output_response_charset_detection and
test_terminal_output_request_charset_detection tests for Big5.

Pin to charset-normalizer>=2.0.0,<3.0.0 until the upstream ranking
regression is resolved.

Fixes #1628
