fix: inconsistent paths and backticks in technical_overview.md file

[kunstewi]

resolves #1051

go to this file and check src/content in the file organisation section.

Issue Summary

1. The localization-architecture.md doesn't exist instead the file name is localization.md. Also there's no backticks.
2. src/[locale]/pages/ path is wrong, instead the correct path is src/pages/[locale]/

Fix Summary

1. The localization-architecture.md file is renamed to localization.md so changed the reference and also the backticks weren't present.
2. The current documentation states src/[locale]/pages/ which is wrong the correct path is src/pages/[locale]

This solves potential confusion for future contributors.
