fix: move ae_adaptor and ae_submitter into deadline namespace

When running pip install deadline-cloud-for-after-effects, it would install ae_adaptor into the site-packages, instead of in the deadline namespace package.
When running the jsxbundler.py on Windows, it would error would with a "\P invalid syntax" on the help text of argparse

include the deadline namespace for targets, this then also includes the ae_submitter in the pip install, even
just swap the slash in the help text

Users can get further in this alpha intergration without experiencing roadblocks immediately.

hatch run fmt
hatch run lint
hatch build
hatch run test

I then pip-installed the local build and confirmed that it put the submitter and adaptor within the deadline namespace.

N/A
