opencv: Update to version 5.0.0, fix checkver

[Izumiko]

• Use conventional PR title: <manifest-name[@version]|chore>: <general summary of the pull request>
• I have read the Contributing Guide

The official OpenCV website's release page is currently not being actively updated. The current opencv manifest relies on the page for its checkver checks. As a result, the Scoop package is significantly outdated (currently stuck at 4.12.0).

Meanwhile, official releases on their GitHub repository are fully up-to-date. They have already released 4.13.0 and the major milestone 5.0.0.

Summary by CodeRabbit

• Chores
  • Bumped OpenCV target to 5.0.0.
  • Updated 64-bit Windows download URL and checksum for the new release.
  • Switched version detection to use the official OpenCV GitHub releases for more reliable updates.

Walkthrough

The OpenCV scoop manifest is updated to target OpenCV 5.0.0; the checkver now uses the OpenCV GitHub repository for version detection and the 64-bit Windows release URL and hash were updated. The autoupdate template continues to use $version for GitHub release assets.

Changes

Layer / File(s)	Summary

Poem

🐰 I hopped from regex through the log,
To GitHub's fields where releases jog,
Version five now in my paw,
Clean and simple—no more claw,
A tiny hop, a quieter cog.
