add support for `testcontainers` 4 for `wiremock[testing]`

[ZeeD]

Proposal

Current wiremock[testing] is bound to testcontainers ^3.7.1, witch - according to https://pypi.org/project/testcontainers/3.7.1/#history is from december 2022.
There have been a lot of changes since then - and it would be useful to be able to use the current version of testcontainers when using this library
