[TASK] Update TypeScript and friends, September 2023

This patch updates `typescript` to 5.2 and `@typescript-eslint` packages
to 6.6. Updating `@typescript-eslint` revealed a broken condition in
the `@typo3/backend/viewport/navigation-container` module that is now
removed.

    npm install --save-dev \
        @typescript-eslint/eslint-plugin@^6.6.0 \
        @typescript-eslint/parser@^6.6.0 \
        @typescript-eslint/typescript-estree@^6.6.0 \
