feat: add `registry` and `owner` parameters to `Image`

[DDtKey]

It's alternative solution for https://github.com/testcontainers/testcontainers-rs/pull/549 A bit more user-friendly because operates with separate entities, but kinda redundant. Instead of configuring 1 parameter to override, users will have to split it to 3.

E.g: gallery.ecr.aws/docker/library/redis should be represented as:

• registry: gallery.ecr.aws
• owner: docker/library
• name: redis

But user actually can just pass gallery.ecr.aws/docker/library/redis to name, or gallery.ecr.aws/docker/library to owner. We can't protect it.

Adds ability to set registry and owner on per-Image basis, and override them with RunnableImage.

Closes #335
