Download page links source code to main branch instead of release tag

[Nathan du Buy -Mealman1551]

Currently, the download page lists "Latest version: 1.4.3" but the Source Code
links point to snapshots of the main branch:

- /archive/refs/heads/main.zip
- /archive/refs/heads/main.tar.gz

This is a moving target and does not correspond to the 1.4.3 release.

For consistency and reproducibility, the source code links should instead point
to the 1.4.3 release tag:

- /archive/refs/tags/v1.4.3.zip
- /archive/refs/tags/v1.4.3.tar.gz
