AWS MWAA v2.10.3 is using pip version 25 while the mwaa-local-runner image is using pip 22.3.1.
I've come across this in an upgrade from AWS MWAA v2.6.3 to v2.10.3. The version 25 of PIP requires PEP440 adherence and "version = latest" is not a valid version in the WHL package(s).
We've had to do some work to get it fixed and valid but this is an inconsistency
