Try to remove duplicate type name 'Platform' and 'Tag'

[McHauge]

Try to remove duplicate type names for 'Platform' and 'Tag' based on my findings using the full file available here: https://vrchat.community/openapi.yaml

Not entirely sure how this file gets assembled, soI have tried to do it as close to what I saw used in other places in the duplicate files

Closes #482

I wouldn't consider this the same tag, it is an explicit union of:

• icon, gallery, sticker, emoji, or emojianimated

Fair, that one makes sense. I don't think that one is one of the ones that gave errors now that I look at it again. Feel free to not include that one.

I have since I made this one also found a couple of missing type definitions. Where the names have been left out, and not being defined in the schema, only local in the one message with out a name for the overall type.

is that something I should add here or would that work better in a separate ticket/pr?

Thsese 3 Schema definitions seems to be missing (and then they will need referencing to their messages):
