Tarballs may not be completely uploaded

[scpeters]

There were errors in two separate attempts to complete the release process for gz-sim 10.2.0, corresponding to the following gz-sim10-source jobs:

• https://build.osrfoundation.org/job/gz-sim10-source/7/
• https://build.osrfoundation.org/job/gz-sim10-source/8/

Each of those -source jobs generated tarball artifacts of size 339.79 MiB (with different sha256 checksums), but in the console output of the repository_uploader_packages jobs, files of smaller size were uploaded to s3, and downstream debbuilder jobs failed to match the sha256 checksum after downloading from s3.

In this case, we downloaded a tarball artifact from the -source job and manually uploaded it to s3 to proceed with this release, but we did not identify the underlying cause of the incomplete tarball.
