Remove legacy import option

[abdnh]

Closes #3493

If a user has the legacy importer enabled and upgrades, isn't this going to leave them with it stuck on? Perhaps we should be making legacy_import_export() always return False as well, and then the add-on can override it?

That crossed my mind, but thought maybe it's a rare case.

The add-on no longer uses the config option. It patches the new importing path instead: https://github.com/johnpincock/SpecialFields/pull/39/files

No more legacy import/export handling in 24.11?

I noticed this since I use u/Glutanimate's Export Deck to HTML and Print to PDF and it relies on the legacy export options. Had to downgrade.

Seems like that user only needs the legacy import option because they use some addons that rely on that.

Wouldn't it be much better to update the addons (or choose alternatives if they exist) then to keep and maintain any legacy option in anki? Not sure if @glutanimate still updates those addons, though.

Add-ons that need legacy handling can be fixed with minor changes (see the Special Fields add-on)
