package nginx 1.27 has wrong version

Describe the bug

Hi, as the nginx 1.26 has several vulnerabilities I tried upgrade it to 1.27 as it is written in https://github.com/vmware/photon/wiki/Security-Update-5.0-307 . The package itseld is in the base repo but it is not installable because the OS states the the upgrade would really be a downgrade.

I think the difference (the missing 1: in the version) between the old package (1:1.26.0) and the new one (1.27.0) causes that the tdnf thinks it is a downgrade.

Reproduction steps

$ tdnf update

$tdnf info nginx
Name          : nginx
Arch          : x86_64
Epoch         : 1
Version       : 1.26.2
Release       : 4.ph5
Install Size  :   1.08M (1130889)
Repo          : @System

...

Additional context

No response

Start by locating the Photon base-repository nginx package definition and inspecting how its RPM epoch, version, and release are set; compare them with the installed 1:1.26.2-4.ph5 and available 1.27.0-1.ph5 packages. Reproduce the issue with the tdnf update, info, upgrade, and local RPM install commands, and confirm that the corrected metadata is treated as an upgrade rather than a downgrade.
