Bug fixes in Review Changes, improved release reference validation, and CLI commands

• When working with documents in a release, document validations will now show the correct error when referencing a document that will be unpublished in the same release.
• Fixes an issue in the "Review Changes" pane which showed all fields in a draft as being erased after a document draft had been published. Now, the pane will show the correct diff comparing the most recent publish with the one prior.
• The sanity build command will no longer fail if the version parameter in the Studio's package.json is missing.
• sanity init can now be run in Next.js projects in unattended (-y) mode.
