Remove Williams (2017 FCA 252): the s. 13 PCMLTFA exception was repealed in 2018

Williams interpreted the 'election not to proceed' exception in PCMLTFA
s. 13, but Parliament repealed s. 13 the year after the decision
(S.C. 2018, c. 27, s. 174). The case is no longer good law on a live
provision, and surfacing it on cross-border currency-reporting queries
risks misleading a user about what the Act now requires. A comment in
canlex/caselaw.py marks the slot so the case isn't accidentally
re-added.

24 chunks dropped (5036 -> 5012). 141-question eval after the removal:
Hit@1 0.79 / Hit@3 0.94 / Hit@5 0.98 / Hit@10 0.99 / MRR 0.87 (vs
pre-removal 0.79 / 0.96 / 0.99 / 0.99 / 0.88 -- small embedding-space
jitter on PCMLTFA s. 18 and IRPA s. 64; the trade is a small precision
dip for legal correctness, the right call).
