Fix broken version check in tbot's `tshwrap` (#13034)

`tshwrap` performs a tsh version check to ensure it has the
functionality we need. Unfortunately, during a final refactoring
before merging, we changed the function signature of `capture()` to
require an explicit path to a `tsh` binary but in a way that was
unfortunately not caught by the compiler. The previous syntax meant
we just tried to execute the first argument, i.e. `version`, which
is never what we want.

This PR correctly passes the tsh path to `capture()` to fix the
version check.
