[Bug]: TESTCONTAINERS_HUB_IMAGE_NAME_PREFIX trailing slash not handled properly

testcontainers / testcontainers-go

Testcontainers for Go is a Go package that makes it simple to create and clean up container-based dependencies for automated integration/smoke tests. The clean, easy-to-use API enables developers to programmatically define containers that should be run as part of a test and clean up those resources when the test is done.

What happened?

If we add a trailing slash to TESTCONTAINERS_HUB_IMAGE_NAME_PREFIX, which we do by convention, Test Containers doesn't handle this very well. All containers end up having something like i.e.:<custom_url>//<image> which causes it to fail.
