Simplify Routes facade methods

[caendesilva]

Wondering if we should take more steps to normalize the API, and match to Laravel. I'm not sure if there is ever really a reason to want a null return here, I think if you don't want to catch an exception, it's better to use Routes::exists to check first. See #591 which was closed due to similar motivations

The current methods as follows:

public static function get(string $routeKey): ?Route
{
    return static::getFacadeRoot()->get($routeKey);
}

/** @throws \Hyde\Framework\Exceptions\RouteNotFoundException */
public static function getOrFail(string $routeKey): Route
{
    return static::getFacadeRoot()->getRoute($routeKey);
}

Could be merged and simplified like this:

public static function get(string $routeKey): Route
{
    return static::getFacadeRoot()->getRoute($routeKey);
}

Considering this is quite a BC break for quite a small thing, we would need to carefully consider this
