Rebuild translation table + support ordered factor in scan_data

[olivroy]

• Update translation file
• Reduce logic around encoding for the translations (this may mean decreased support for Windows 4.1 and below, but I don't see any reason why to still use R<4.2 on Windows, it solves a lot of problems)
• Remove workaround for R < 3.2
• Support ordered factors
• Correct some translations
• update links to repo

This example was motivated by this example

scan_data(ggplot2::diamonds[1:100, ], lang = "fr", sections = "v")

Before:

Also the link at the bottom was a dead link:

This PR:

(notice that factor shows up) and FR translation is correct.

Links updated

The initial reason why I pursued this was the link, but the translations + support for ordered factor is a good addition!

@rich-iannone Ready for review!

With #581, I convinced myself that translations currently don't work correctly on Windows R < 4.2. Therefore, I am more confident with my changes here.

• I updated some FR translations
• Update the translations RDS file (it was already out of date)
• Update links to avoid the old repo address
• Remove a workaround for very old R
• Remove complex logic around encoding (It didn't work for me out of the box + doesn't seem to change anything)

LGTM!
