[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:

How to update
=============
How to update depends on the :ref:`installation` method. If you have used the
:ref:`installation scripts`, use the ``update`` command from the :ref:`searxng.sh`
script.
.. code:: sh
sudo -H ./utils/searxng.sh instance update

How to inspect & debug

SearXNG is a *rolling release*; each commit to the master branch is a release.
SearXNG is growing rapidly, the services and opportunities are change every now
and then, to name just a few:
- Bot protection has been switched from filtron to SearXNG's :ref:`limiter
<limiter>`, this requires a :ref:`Valkey <settings valkey>` database.
- To save bandwidth :ref:`cache busting <static_use_hash>` has been implemented.
To get in use, the ``static-expires`` needs to be set in the :ref:`uwsgi
setup`.
To stay tuned and get in use of the new features, instance maintainers have to
update the SearXNG code regularly (see :ref:`update searxng`). As the above
examples show, this is not always enough, sometimes services have to be set up
or reconfigured and sometimes services that are no longer needed should be
uninstalled.
Here you will find a list of changes that affect the infrastructure. Please
check to what extent it is necessary to update your installations:
:pull:`1595`: ``[fix] uWSGI: increase buffer-size``
Re-install uWSGI (:ref:`searxng.sh`) or fix your uWSGI ``searxng.ini``
file manually.
Check after Installation
------------------------
Once you have done your installation, you can run a SearXNG *check* procedure,
to see if there are some left overs. In this example there exists a *old*
``/etc/searx/settings.yml``::
$ sudo -H ./utils/searxng.sh instance check
SearXNG checks
