Make
riverdriver/riverpgxv5 its own submodule (#3)
Here, make `riverdriver/riverpgxv5` its own submodule. This does nothing for the time being since the top-level River package is entirely dependent on `riverpgxv5` as the only driver (and its used in examples and tests), but the general idea is that in the future each driver could bring in its own dependencies, and applications using River wouldn't have to pull in every 3rd party database package that River supports. The only problem is that there's a tradeoff: the way I had `riverpgxv5` before is that it referenced `riverdriver.Driver` and made use of an `internal.Sentinel` value from the top-level package to guarantee no one could implement the driver interface externally. That no longer works because it introduce a dependency cycle: `river` needs `riverpgxv5` and `riverpgxv5` needs `river`. So I can remove the top-level types referenced in `riverpgxv5` so the dependency only goes one way, but we lose `internal.Sentinel`, and can no longer guarantee that `Driver` isn't implemented. So put simply: `riverpgxv5` gets its own module, but we move to only a soft guarantee that external users don't implement `Driver` (we spell it out in the docs, but there's nothing technical preventing people from doing it). Overall: I think it's probably worth it. It's pretty clear `Driver` isn't meant for external implementation, there's no advantage to doing so, and the interface is already a little leaky because users could technically call functions on the interface already like `GetDBPool()` and break themselves as those disappear in the future.
