BIP345: fix OP_SUCCESS188 hex value

[shesek]

OP_SUCCESS188 is 0xbc, not 0xbb.

ACK c532b53, OP_SUCCESS188 is constrained with new rules in this BIP to implement OP_VAULT_RECOVER and 188 is 0xbc.

Pinging @jamesob and @instagibbs for approval.

I was wondering whether it was obvious whether OP_SUCCESS187 was meant and 0xbb was correct, or whether OP_SUCCESS188 was correct and 0xbc was the typo.

As the line corrected in this PR follows another prior mention that introduces the two new opcodes, and the introductions of the paragraphs repeat except in the opcode name, it seems clear that the lower mention is a copy error from the previous header, and I agree that that this is correct.

The tapscript opcodes OP_SUCCESS187 (0xbb) and
OP_SUCCESS188 (0xbc) are constrained with new rules
to implement OP_VAULT and OP_VAULT_RECOVER,
respectively.

The reference implementation also confirms this interpretation:

Merging.
