fix(dataviews): drop generic JSX syntax from registerLayout story

`<DataViews< PaymentMethod >` is a valid TS-in-JSX generic call form,
but no other Gutenberg story uses it. Some Storybook/Babel setups don't
parse it, which can silently drop the story from the sidebar. Rely on
inference instead, matching the existing story convention.
