WebLink: Forward text prop to ZulipText, fixing CustomProfileFields crash

This fixes a regression introduced in 72280dd, released in the
v27.198 beta. The underlying ZulipText was throwing its error

  `text` or `children` should be non-nullish

when the user navigated to a profile screen that tried to render a
"link" type custom profile field, such as a GitHub link.
