fix: Enforce Locale.US for AwsRequestSignerTest (#1111)

jmahonin · web-flow · commit aeb12182241e · 2022-12-13T16:05:37.000-08:00
Date parsing can fail in other locales.

Specifically, in `en-CA` (Canada), the tests's defined date `Mon, 09 Sep 2011 23:36:00 GMT` won't
parse correctly, as the weekday short name for the locale is `Mon.` (extra period).
