Hi! I love this library, thanks for making it available!
I'm having an issue on one of my two machines but I can't figure out the root cause. I have been using the library for several months now and it was working however a few days ago, my test container wouldn't start on one of my machines. On another machine it still works well. I tried comparing the Docker versions but there doesn't seem to be an obvious difference. (I'm a relative docker n00b though.)
What's happening is that the start() method is throwing an error and not starting.
I'm not sure exactly what would be helpful for you to know so I'll put some relevant information below. I don't really think it's your library but I'm wondering what other dependencies I should look at to see what the issue is.
Thanks so much!
Here is a readout of my terminal output.

info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.I have traced this back to the testcontainer library's generic-container.ts file's waitForContainer method. I have run the debug logs for testcontainer and it seems that the container health checks are starting but not completing.
I also do not see the logs from the wait strategy's waitUntilReady method so I believe the error is being thrown on the withStartupTimeout method or the early in the waitUntilReady method.
