v4.5.5-<sha> Releases

This version of codecov contains the following SHA'd releases for web and worker as well:

worker: codecov/enterprise-worker:v4.5.5-49013fc
web: codecov/enterprise-web:v4.5.5-6727ba4

Specifically these SHA'd releases of v4.5.5 contain all of the above changes, but also bring in version 6.0.0 of the minio-python SDK dependency (changelog).

Version 6.0.0 of the minio-python SDK was included because it makes some key operational and quality of life changes to those users leveraging IAM auth in AWS for their Codecov Enterprise install. If you leverage minio's IAM auth functionality in your Codecov Enterprise install, and you have been having difficulties related to key rotation, you are recommended to use this release. Otherwise, v4.5.5 is very likely sufficient for your needs.

The minio changes in this SHA'd release will be rolled into a future main release of Codecov Enterprise, v4.5.6 or later.
