**Describe the bug** In the readme on https://github.com/testcontainers/testcontainers-python/blob/main/core/README.rst the documention citates there should be a `DockerImage` with `from testcontainers.core.image import DockerImage`. But it is missing for me in the package. If i install the current version with poetry file is missing. Also downloaded from https://pypi.org/project/testcontainers/4.5.1/#files and looked in the gz file. The file is missing, too. My Download path is https://files.pythonhosted.org/packages/ac/61/1057fa25b341e97e45a47f71aad08f7ab82beaeed51c3014932627d3ec54/testcontainers-4.5.1.tar.gz The file is in this repository but not in the final build (it seems). Is the documentation up to date? **To Reproduce** Download current package and look for the file **Runtime environment** - win 10 - python 3.10 - Poetry 1.8.3
