• Added tests for changed code.
• Updated documentation for changed code. (No docs change needed: the docs never said names were case-sensitive.)

from_format builds its regex from the locale's month and weekday names and then looks the matched text up by exact value, so 14nov22 with DDMMMYY raises String does not match format while 14Nov22 works.

This wraps the name tokens (MMMM, MMM, dddd, ddd, dd) in a scoped (?i:...) group in Formatter._replace_tokens, and makes Locale.match_translation compare lowercased values. Other tokens (T, Z, A) keep their current case rules. match_translation is only called from from_format parsing.

Fixes #668 (also covers #809).

Ran live: pendulum.from_format('14nov22','DDMMMYY') -> 2022-11-14 00:00:00+00:00 (raised ValueError before).
