fix: improve lingui configuration (#1388)

## Description

Currently merge conflicts arise due to the compiled JS and PO
translation files.

This PR is a rework on how we handle extracting and compiling
translations to streamline PRs and merging branches.

## Changes Made

- Remove compiled translation files from being committed
- Extract and compile translations only on build
- Extract will still occur when commits land on main to sync and pull
new translations with Crowdin
