Bump schema version from 2 to 3

[joshuafredrickson]

Version 3 is now supported in WordPress 6.6.

Migrating from v2 to v3: https://developer.wordpress.org/block-editor/reference-guides/theme-json-reference/theme-json-migrations/#migrating-from-v2-to-v3

Type of change

PATCH: backwards compatible change

This doesn't appear to break anything. Although, there are migration steps in the link above that add two default values: settings.typography.defaultFontSizes and settings.spacing.defaultSpacingSizes.

Sorry for the delay! This looks great & thank you for your work on it.

Looks like the tests are failing, which is good. Could you run the following two commands and commit the new snapshots?

yarn @bud test unit --update
yarn @bud test integration --update

Sure thing! Ran them and committed, but bumped into an AWS access key error on tests/reproductions/issue-2574.test.ts.

Any updates on whether this will be implemented soon? 6.7 will be released today and it's quite important to be using theme.json schema version 3 to have access to new properties
