add py wheel package to urlshortener action

[troyready]

Aiming to elminate errors from GH actions logs like:

Could not build wheels for boto3-stubs, since package 'wheel' is not installed.

Seen in this GH action run.

Not certain it's related to subsequent Union error -- I couldn't reproduce it in my own quick test.

we can also remove boto3-stubs from the prod dependencies by changing the import in the script to something like this to make it more resilient.

if TYPE_CHECKING:  # only req boto3-stubs as a dev dependency
    from mypy_boto3.boto3_session import Session
    from mypy_boto3_dynamodb.service_resource import Table
else:
    Session = object
    Table = object
