Fix an issue with updatePackageJsonInEditorState (#6333)

**Problem:**
`updatePackageJsonInEditorState` was providing incorrect arguments to
the `codeFile` factory function when updating the package.json file.

**Fix:**
Fix it.

**Side note:** IMO the `codeFile` function should always be
`RevisionsState.CodeAheadButPleaseTellVSCodeAboutIt` by default, since
it is typically used as a convenient way to create a new `TextFile` from
the design side of Utopia. However, I tried making that change and it
broke far too much of the editor, somehow resulting in the project
contents being entirely wiped, so I'd rather just leave it be for the
moment.

**Manual Tests:**
I hereby swear that:

- [x] I opened a hydrogen project and it loaded
- [x] I could navigate to various routes in Preview mode
