Fix empty bulkCartUpdate typing in docs

[vctrchu]

Resolves https://github.com/Shopify/shopify-dev/issues/53252

Background

The omit operators don't play well when generating dev docs. I will update the type to exclude the variables instead. Since the docs are evaluated based on the interfaces, they are no generated json file diffs. I ran npm run docs:point-of-sale to be sure.

[github-actions]

We detected some changes in packages/*/package.json or packages/*/src, and there are no updates in the .changeset directory. If the changes are user-facing and should cause a version bump, run yarn changeset to track your changes and include them in the next release CHANGELOG. If you are making simple updates to repo configuration, examples, or documentation, you do not need to add a changeset.

Can you lodge this as a bug with the team that makes the doc generation tooling?

Just to add to this, it would be great to get some examples for creating, editing, and deleting these cart items in bulk, too. With this PR, the docs are added, but it's still not clear how to use them and what the use cases are.
