Refactoring the web translations (#1777)
## Problem

- The web translations still use the original Cockpit mechanism for
creating and loading the translations
- That uses a server based logic which has quite some drawbacks
- We have to reimplement the very same logic in a Webpack plugin to make
it work also in the local development server (`npm run server`). And
unfortunately we cannot share the code because it is Rust vs.
Javascript...
- This will not work in the Agama online demo site with completely
static files (without any server side logic, everything needs to be on
the client side).
- For me the original logic was quite strange, why the server should
decide which translations should the client use? It should be completely
handled on the client side, there is no reason for the special server
logic. The server should just report the available translations and let
the client to pick and use the right one.
- The old implementation has also some ugly parts like requiring a
global Javascript variable...

## Solution

- Move the translation logic from the server to the client (browser)
- Use dynamic imports instead of HTTP redirection

## Implementation details

- Removed the `po.js` handler from the Agama HTTP server
- Removed the `po.js` handler from the Webpack development server
- Removed the original Gettext PO files from Git, replaced by already
converted JS files
- Removed the Cockpit Webpack plugin for converting PO files to JS,
replaced by a simple script with similar functionality. (As a bonus the
code was fixed to avoid adding unnecessary `null` values into the
output.)
- Added dynamic import for downloading the requested translations
- Some code cleanup (removing the global JS object)
- Moved the `jed` and `gettext-parser` NPM dependencies to the PO->JS
converter, that means those NPM packages are installed only when
converting the PO files to JS (basically only in the GitHub action which
merges them), they are not installed when building the Agama web
frontend

## Testing

- Tested manually, loading the translations works fine 
- I manually triggered the GitHub Action which merges the translations
from Weblate. It works fine, the test run opened this [pull
request](https://github.com/agama-project/agama/pull/1780) with updated
translations (there are more changes as it was executed in the same
branch as this pull request).
