fix(core): add container logs to TimeoutError when wait strategy times out

[ticapix]

Hello,

Thanks for testcontainers !

I had a lot of trouble to understand why my docker strategy was timing out and I ended up patching the code like in this PR to get the container logs when there is a timeout.

I hope it can help others when debugging.

make tests runs ok

Happy to update the PR if needed
