Improved Content Release error highlighting, and bugfixes for Visual Editing with Portable Text

This release improves error navigation in content releases by jumping directly to problematic fields and fixes issues with geopoint field configuration and Portable Text block editing.

Keep track of which Sanity Plugins support Studio v6

Clicking the validation error icon for a document in a Content Release now opens the document and jumps to the offending field, instead of only showing an error count.

• Geopoint field options now support collapsible and collapsed, so geopoint fields can be configured as collapsible without a TypeScript error.
• Fixes a bug where, in Presentation / Visual Editing, you could not re-enter a Portable Text block by clicking it again in the preview after editing it and then clicking another element such as the document title. The editor now scrolls to and re-focuses the block on the repeated click.
• Updates @sanity/schema, @sanity/types, @sanity/codegen, @sanity/import, and @sanity/migrate in @sanity/cli, and @sanity/schema and @sanity/types in @sanity/cli-build, to versions compatible with Sanity v6.
