misc: replace all "Metadatas" with "Metadata"

[swalahamani]

Breaking changes

• We replaced all API containing metadatas with metadata. This includes but is not limited to:

  • themeConfig.metadatas
  • Layout.Props.searchMetadatas
  • @theme/SearchMetadatas

  If you use any of these APIs, you need to update accordingly.
  Why? Because metadatas is grammatically incorrect. We are not going to pretend like we are grammar masters who made this API with a surprising purpose—we are just wrong, and now we fix it.

Motivation

The plural form of Metadata is Metadata itself and not Metadatas.

I don't really know... I also have some objection to "metadatas" but we use it here and there. I'm going to use this chance to run a global search & replace

@slorber What do you think? I think there are only two worlds: (a) we close this PR and do nothing and pretend we are grammar masters and (b) we fix all "metadatas" including the themeConfig API and release this as BC. I don't think fixing this in the docs without fixing it in the code is worth it and just leads to more confusion.

[slorber]

It's my fault, used to think metadatas was correct 😅

I'm ok to change it everywhere, including a breaking change in theme API considering we'd rather do that before 2.0

[Josh-Cena]

Actually, I did a random chat with someone else and they said metadatas is acceptable :P

If you have a concept of metadata, and metadatas is an array of that, I think it's perfectly fine
I could see an argument that metadata is a group of metadatums, and metadatas is a group of multiple metadatums

But anyways, fixing it seems more sensible
