feat: adds ability to copy data from across locales

[JessChowdhury]

What?

Adds ability to copy data from one locale to another at a document level.

Feature request can be found here.

[Internal] Design here.

How?

For any localized collection, you will find a new option in the document controls called Copy to Locale.

This option will open a drawer, from here you can select your origin and destination locales.

If data already exists in the destination locale, you can choose to:

1. Overwrite this data (this will copy any empty fields in your origin locale)
2. Not overwrite existing data (this will only copy data into empty fields in the destination locale)

You can change your selection using the following checkbox:

Looks good other than the error handling and translation todo. Nice work!

I was going ot merge this but then I noticed there are a handful of missing translations to fix.
unsavedChanges: undefined,

Do you want to take care of that before I merge?

I tried to test the feature with blocks and it errored for me.
This was taken from our test/localization suite working with the Nested Arrays collection.

I'm not sure if this is because the collection has versions enabled or if it was nested data that couldn't be handled.

Aside from this, I have UX concerns about this feature as it would be too easy for a user to click the wrong locale and overwrite some existing data. It feels to me like we should have a modal or something to add an additional step for acknowledging that they might be overwriting everything in a document on the target locale.

The copy button should look more like a secondary actions with dropdown options like this:

copy button appears and was moved into actions popup
