small documentation updates for N5 and Neuroglancer Precomputed

[hotzenklotz]

As a follow up to PR #7578, I added some more small documentation "hints" for support of N5 and Neuroglancer precomputed datasets when uploading datasets.

Additionally I fixed a antd warning. <Spin tip={"Some text"} /> requires the use of children. See docs https://ant.design/components/spin. Additionally the "spin" text would be stacked vertically, because the <Spin /> did not have enough width / no-width defined at all. By wrapping the whole modal this can be fixed - even though it is not the prettiest solution. Anyway, this spinner should only ever be visible for a short time anyway if at all.

With fix:
