Swap em dash for hyphen in pagination summary (ENG-3360)

[sahajgandhi-deeptrust]

Summary

ENG-3360 removes em dashes from customer-facing UI copy. Pagination renders the only one in this package's shipped copy, so every paginated table in web showed it:

-`Showing ${itemFrom} — ${itemTo} of ${totalItems}`
+`Showing ${itemFrom} - ${itemTo} of ${totalItems}`

Character swap only. Remaining em dashes in lib are in code comments and a Storybook story's placeholder, which aren't customer-facing. Consumed by deeptrust-ai/web#812, which bumps the submodule pointer to this commit.
