Remove direct python 3.8 dependencies from dagster-cloud-action now t…

…hat it is EOL

Summary:
- Don't install python 3.8 in every serverless build unless that version is what is being used
- Use python 3.11 instead of 3.8 in the manylinux builder

Test Plan:
Create a release and run the action on a serverless deploy ofpython 3.8 through 3.12
Run a docker build locally using the latest manylinux builder
