It doesn't matter if you're using Mullvad's VPN and a proper browser, you'll
still get blocked for specific searches [1] with a 403 or 429 HTTP status code.
Mullvad only blocks the search request and doesn't prevent you from doing more
searches.
The logic should handle the blocked requests (403, 429), but not put the engine
on a cooldown.

Re-writes the Mullvad Leta integration to work with the new breaking changes.
Mullvad Leta is a search engine proxy. Currently Leta only offers text search
results not image, news or any other types of search result. Leta acts as a
proxy to Google and Brave search results.
- Remove docstring comments regarding requiring the use of Mullvad VPN, which is
no longer a hard requirement.
- configured two engines: ``mullvadleta`` (uses google) and
``mullvadleta brave`` (uses brave)
- since leta may not provide up-to-date search results, both search engines are
disabled by default.
.. hint::
Leta caches each search for up to 30 days. For example, if you use search
terms like ``news``, contrary to your intention you'll get very old results!

A recent update from Mullvad Leta introduced the img_elem. This update
broke the existing logic. Now, by checking the length of the dom_result
to see if it was included in the return results, we can handle the logic
accordingly.
