Missing information on how to get localization working on Linux images

### Description

The page is missing information on how to get localization working on Linux.

From what I can gather, when using the official "alpine" images in Docker/Kubernetes the following packages must be installed:
- icu-libs
- icu-data-full
using the `apk add --no-cahce icu-data-full icu-libs` command and then setting the environment variable as documented in this page.

Failure to install *both* packages will make the code run without exception but won't do the actual localization.
