adminer-pematon: init at 4.12

Link: https://github.com/pematon/adminer

This is an active fork of adminer by pematon.
Seems to be in rapid development.

The index.php is required for plugins to work, and the upstream provides an example, but not a ".php" file in the src. We need to modify it for NixOS use anyway.

The index.php file is the same one used by adminerevo, I wasn't sure if I should reference a file out of the package's dir, so I copied it here.

Closes #353454

@ofborg build adminer-pematon

Closes #353454, I originally wanted it to replace the original adminer, but since it didn't gain interest, let's init the fork as a separate package

Opinionated: I would modify this into something more functional, like:

<?php

declare(strict_types=1);

namespace nixos {
    use AdminerPlugin;

    use function sprintf;

    function adminer_object(): object
    {
        require_once __DIR__ . '/plugins/plugin.php';

        if (!file_exists(__DIR__ . '/plugins.json')) {
            return new AdminerPlugin();
        }

        $plugins = array_map(
            static function (string $name): ?object {
                $plugin = sprintf('%s/plugins/%s.php', __DIR__, $name);

                if (!is_readable($plugin)) {
                    return null;
                }

                require $plugin;

                preg_match_all('/(\w+)/', $name, $matches);

                return new sprintf('Adminer%s', implode('', array_map('ucfirst', $matches[1])));
            },
            json_decode(file_get_contents(sprintf('%s/plugins.json', __DIR__), true))
        );

        return new AdminerPlugin(array_filter($plugins));
    }
}

Done, thanks, tested and it works.

One thing I might add though, do you know perhaps a way to override to use adminer-theme?

I am currently removing the index.php provided by this package, and adding an index.php with modifications for adminer theme.
