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.
