siteconfig: correct the retired-queue-manager archive's stale summary

Its closing paragraph still listed SGE as supported, which stopped being
true later the same day, and implied that being listed in QueueManagers
meant a manager worked. It did not: PBS and LSF emitted Cray NQE/NQS
syntax and Moab emitted nothing at all until today. Record that, and the
rule that fell out of it -- generate a script and read it before believing
the list.

+Update 2026-09-22, after actually generating a script for each of them:
+being listed in QueueManagers was never evidence that a manager WORKED.
+The PBS and LSF directive blocks in submit.site were Cray NQE/NQS syntax
+that no current scheduler accepts ("-lM 28Mw", "-lT 7200", the
+mpp_t/p_mpp_t/mpp_p resource names, "-J m", a lowercase "-s" for the
+shell, and "-r $submitFile" where PBS's -r is the restartable flag and
+LSF's is rerunnable, neither being the job name). The Moab block was
+empty outright, so Moab jobs carried no directives at all. All three have
+been rewritten; only Slurm has been checked against a real scheduler's
+documentation on this machine. If you are adding a manager, generate a
+script and read it before believing the list.
