Mod update check is inaccurate

Bug Report

Summary

Our current mod update check is very approximate and can result in inaccurate update data and unexpected behaviour.

Steps to reproduce

SMAPI:

• Download SMAPI 3.18.2
• Press update button
• 4.0.8 will be installed rather than 4.1.10 or grater

SpaceCore (https://www.nexusmods.com/stardewvalley/mods/1348?tab=files):

• Download 1.2- SpaceCore - 1.0.1
• No updates are detected instead of getting the latest one
• Download 1.16.1
• Press download update
• 1.27.0 is downloaded correctly
• but download update button is still available
• pressing button again downloads 1.23.1?

This was a case I tested in development.

Chances are, something changed when main branch got merged not too long before merging into main. Probably something very trivial, I'll bisect and get it sorted when am feeling a bit better in my head.

Would also be a good idea to write tests around this, given the opportunity.

Sorting this right now.
Wow, I can repro, how weird.
