fix: scraper of unity versions

[webbertakken]

Changes

• Fix selector and correct url for scraping Unity Editor versions.
• Fixes Images missing for Unity 2022.2.0f1 and 2022.1.24f1 docker#193 (although, note that 2020.2.x might not be compatible with our current setup yet, as requirements changed.)

How to test:

Go to Unity Editor archive page and run this in your console:

document.querySelectorAll('.release-links div:first-child a[href]').forEach(link => console.log(link.href))

Wondering if now would actually be a good time to switch to scraping via their artifact server rather than trying to scrape their front end which changes style.

Great suggestion.
For now I'm pretty happy with the "proven to work" way as this is a relatively easy fix.

Note that one of the releases has missing mono.pdb from previous releases inside the version field.

Looks good to me 🚀
