Allow alternative option for legacy shader armors

[LoneDev6]

A new option equipment.legacy_armor_rendering_id will be integrated into the new equipment attribute of the items to allow creating armors that use both the legacy shaders method and the new equipment tag.
Examples are available on the issue page #3980 .

armors_rendering will accept also legacy_armor_renderings, which is more descriptive.

All these changes are reflected in the vscode extension.

add an auto-convert option in the settings, an option that does this conversion automatically, would that be possible?
