Describe the bug
A clear and concise description of what the bug is.
I encountering an issue with the filename of a Debian (deb) package in a Pulp 3 repository, where an additional character "1:" is being added after the underscore.

Actual deb package name in Source (remote) location:
http://us.archive.ubuntu.com/ubuntu/pool/main/libx/libxcomposite/libxcomposite1_0.4.5-1build2_amd64.deb

Sync and Published deb package name in pulp3 repository: (Adding 1: character after underscore in filename)
http://x.x.x.x:24816/pulp/content/prod/ubuntu/2204/pool/main/libx/libxcomposite/libxcomposite1_1:0.4.5-1build2_amd64.deb

To Reproduce
Steps to reproduce the behavior:
pulp deb repository sync --name <deb_repo_name> --mirror
pulp deb publication create --repository <deb_repo_name> --structured --version 1 --signing-service 'Pulp QE'
pulp deb distribution update

Expected behavior
A clear and concise description of what you expected to happen.

The pulp3 published repository package name should be same as source(remote) deb package name.. should add any additional characters..

Additional context
Add any other context about the problem here. Please provide links to any previous discussions via Discourse or Bugzilla.

Start by reproducing the issue with the listed pulp deb sync, publication, and distribution commands, then compare the source and published package filenames. Trace how pulp_deb handles Debian package versions during synchronization and publication; done means the published filename matches the source without the added "1:" character.
