vim_configurable: Add wrapGAppsHook for GTK 3 (#44645)

As suggested by @jtojnar in GitHub issue #44580, this patch adds the
package `wrapGAppsHook` to the dependencies (specifically, the
`nativeBuildInputs`) of `vim_configurable`, when `vim_configurable` is
built against GTK 3.

This change prevents GVim from crashing if one tries to use its
file-choosing dialog, and fixes a warning that otherwise might be
emitted if one tries to use its find/replace dialog.
