To complete a SearXNG developer environment, nvm needs to be
installed (ensured).  Without this patch::

    $ LANG=C ./manage dev.env
    ...
    ./utils/lib_nvm.sh: line 27: .nvm/nvm.sh: No such file or directory
    ./utils/lib_nvm.sh: line 28: .nvm/bash_completion: No such file or directory
    ...
    (dev.env)$

We get some good stuff without uvloop, 13MB~ less of dependencies, 3
minutes of build time for armv7 saved, and we are one step closer to NT
compatibility. Although it's true that theoretically the raw performance
have worsened on network side (we only used uvloop for that), the latest
cpython versions have been improving on asyncio performance.

Implement rules and functions to format shell scripts:

    $ make format.shell

or alternatively to format all source code:

    $ make format

The formatter `shfmt` reads the rules from the editorconfig[1]

  If any EditorConfig files are found, they will be used to apply formatting
  options.  If any parser or printer flags are given to the tool, no
  EditorConfig files will be used.

The new ``requirements-server.txt`` (granian) is installed into the virtualenv
of Dockerfile.

When ``make run`` is called, a granian server is started with auto reload on
application's files changes / requires granian[reload] extra, see
``requirements-dev.txt``.

Dependabot supports updates to any ``.txt`` file [1].

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
