Accept closure for backup/restore commands

[timkelty]

Description

• adds \Closure as an accepted type for \craft\config\GeneralConfig::$restoreCommand and \craft\config\GeneralConfig::$backupCommand
  • function(ShellCommand $command) => ShellCommand
• adds \craft\config\GeneralConfig::$backupCommandFormat (pg only) for using archive format
  • also changes restore to use pg_restore to be compatible with create dumps
  • changes extension to be .dump

Example usage

<?php
use craft\config\GeneralConfig;

return GeneralConfig::create()
    ->backupCommandFormat('custom')
    ->backupCommand(fn(\mikehaertl\shellcommand\Command $command) => $command
        ->addArg('--clean')
        ->addArg('--if-exists')
    );

Notes

• For MySQL, both the "schema dump" and the "data dump" get passed through the \Callable. This would allow someone to have different behavior in either one by looking for --no-data or --no-create-info.
• It might make more sense to have backupCommandFormat be in \craft\config\DbConfig, but it felt weird to have it separated from backupCommand.
