OH2 online docs - Download pages omit addons-legacy.kar

[Rossko57]

Current OH2 "Download" docs - https://v2.openhab.org/download/ don't offer links to addons-legacy.kar which as I understand it is still needed for use of OH1.x addons with OH2.

I imagine this fell out during the remote repository changes.

It has been removed here: https://github.com/openhab/website/pull/282/files#diff-6ec5e8b56d0c9949a4bfd560aee2c4fcbf98cdbb695d2eeb5439b4d23d1c187dL417 (for the main page and the page then got introduced into v2 page for a refactoring).

We can reintroduce it and remove some vue logic aside. We don't need the separation between stable and snapshot anymore since v2.openhab.org will only provide docs and download for the stable version.

This seems to be the best way to go. The v2 branch was created for that purpose and should any update occur on main, v2 should rebase cleanly even with these changes.
