Setting ryuk.container.timeout causes a ClassCastException

[jamieswogger]

Tried setting ryuk.container.timeout by creating a testcontainers.properties that contains the following:

ryuk.container.timeout=120

This is successfully picked up, but when TestcontainersConfiguration#getRyukTimeout is called is calls properties.getOrDefault, which returns a string "120" which is attempted to be cast to an Integer. This results in the following error:

java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Integer

A fix for this is to change TestcontainersConfiguration#getRyukTimeout to

public Integer getRyukTimeout() {
    return Integer.parseInt((String) properties.getOrDefault("ryuk.container.timeout", "30"));
}

I've created a pull request with the proposed fix. If that PR is approved and merged is it possible to release a patch soon with this fix?
