Support platform linux/arm64

[rstiller-mw]

if I'm not mistaken, there is currently no arm64 image available of the plugin.
Could you please build and push the current version with --platform linux/arm64?

Thanks!

Sorry for the extensive delay - this repo is not under active maintenance.

As per #32 I'm proposing that this repository be formally archived; if you need to continue using it you're welcome to fork, but it's become unviable for me or the Testcontainers team to maintain.
