Update DatabaseQueue.php

PlanetScale provides great serverless MySQL-compatible database and guide on how to integrate it in Laravel (https://planetscale.com/docs/tutorials/connect-laravel-app) but under hood uses Vitess.

However it looks that Vitess doesn't support "skip" queries:
```SQLSTATE[HY000]: General error: 1105 syntax error at position 185 near 'SKIP' (SQL: select * from `jobs` where `queue` = default and ((`reserved_at` is null and `available_at` <= 1662479913) or (`reserved_at` <= 1662479823)) order by `id` asc limit 1 FOR UPDATE SKIP LOCKED)```

Following laravel#31536 I've improved engine/version parsing for Vitess so it wouldn't use locks for popping:
```>>> DB::connection()->getPdo()->getAttribute(PDO::ATTR_DRIVER_NAME)
=> "mysql"

>>> DB::connection()->getPdo()->getAttribute(PDO::ATTR_SERVER_VERSION)
=> "8.0.23-vitess"```
