First run times out locally, but not in CI

[sernaferna]

I'm experiencing test timeouts on my local machine, but only on the first run after a clean setup. The cause seems to be the time it takes to pull the required images, as subsequent runs pass once everything is cached.

The strange part is that our GitHub Actions pipeline never has this issue. The tests always pass there.

This leads to two questions:

1. Is there a known reason GHA runners might be more resilient to initial pull times (e.g., faster network, pre-cached layers)? I want to understand if my CI pipeline is at risk of failing in the future.
2. Not the end of the world, but is there anything I can do locally to accommodate these initial pulls? I already have fairly significant timeouts in some cases, so I'd prefer not to go even higher (unless people regularly have huge timeouts when using TestContainers). Is there a specific startup timeout property I should be adjusting, aside from the individual test suites/cases?

For what it's worth, I've seen this behavior on both Windows 10 and Ubuntu locally.
