perf(intl): lower log level for language pack cache

[10xLaCroixDrinker]

Description

Lower language pack cache log level from info to debug

Motivation and Context

The using cache log can be printed several times per request and when working, the setting cache logs can be very large & will repeat every 10 min. The existing setting cache log does not work since pino migration.

Removing these from the default log level used in production will improve performance as well as DX (for reviewing logs).

Closes #29
