fix(dap): bound the debugpy import probe with a timeout

The probe runs synchronously on the :Dap* setup tick; a hung interpreter
(dead network FS, broken shim) would block the editor indefinitely. wait(5000)
SIGKILLs the probe on timeout with exit code 124 (:h SystemObj:wait()), which
the existing non-zero check already treats as a failed probe, so resolution
falls through to the remaining candidates.
