chore(sanity): fix resolveUploader typings

[bjoerge]

Description

Fixes a ts-error that started occurring after upgrading to latest @sanity/ui (see https://github.com/sanity-io/sanity/actions/runs/6148137123/job/16681186526)

I didn't investigate why it suddenly started happening, but my hunch is that latest @sanity/ui fixes a typing issue that surfaces a bug with our own typings. This PR works around the issue with an any for now.

What to review

• Type checker is happy

Notes for release
