[mod] migrate from Redis to Valkey (#4795)
This patch migrates from `redis==5.2.1` [1] to `valkey==6.1.0` [2].

The migration to valkey is necessary because the company behind Redis has decided
to abandon the open source license. After experiencing a drop in user numbers,
they now want to run it under a dual license again. But this move demonstrates
once again how unreliable the company is and how it treats open source
developers.

To review first, read the docs::

    $ make docs.live

Follow the instructions to remove redis:

- http://0.0.0.0:8000/admin/settings/settings_redis.html

Config and install a local valkey DB:

- http://0.0.0.0:8000/admin/settings/settings_valkey.html

A Valkey_ DB can be connected by an URL, in section :ref:`valkey db` you will
find a description to test your valkey connection in SearXNG.
``url`` : ``$SEARXNG_VALKEY_URL``
URL to connect valkey database. `There are several ways to specify a database
number`_::
valkey://[[username]:[password]]@localhost:6379/0
valkeys://[[username]:[password]]@localhost:6379/0
unix://[[username]:[password]]@/path/to/socket.sock?db=0
When using sockets, don't forget to check the access rights on the socket::
ls -la /usr/local/searxng-valkey/run/valkey.sock
srwxrwx--- 1 searxng-valkey searxng-valkey ... /usr/local/searxng-valkey/run/valkey.sock
In this example read/write access is given to the *searxng-valkey* group. To
get access rights to valkey instance (the socket), your SearXNG (or even your
developer) account needs to be added to the *searxng-valkey* group.

======================
To set up a local Valkey_ DB, set the URL connector in your YAML setting:
.. code:: yaml
valkey:
url: valkey://localhost:6379/0
To install a local Valkey_ DB from package manager read `Valkey-Installation`_
or use:
.. code:: sh
$ ./utils/searxng.sh install valkey
# restart your SearXNG instance
