#36155 doc: remove json quoting from gettxoutsetinfo and getblockstats cli examples

• Remove redundant inner quotes from CLI help examples for gettxoutsetinfo and getblockstats
• Reduces visual noise and makes help text easier to read for CLI users

Updates the bitcoin-cli usage examples in gettxoutsetinfo and getblockstats help output to omit redundant inner quotes around blockhash arguments. This follows a previous change that allowed bitcoin-cli to accept arguments as plain strings instead of requiring JSON-escaped strings.

Problem: Help text examples for gettxoutsetinfo and getblockstats retained nested quotation marks that are no longer necessary for CLI users, adding visual noise to example commands.

• P4 because it is a minor readability cleanup in CLI help text
• The existing examples were already valid, so no broken guidance is fixed

This PR removes unnecessary JSON inner quotes from CLI help examples for gettxoutsetinfo and getblockstats in src/rpc/blockchain.cpp. It follows up on prior work that allowed CLI arguments to be passed as raw strings rather than escaped JSON strings. The problem is purely cosmetic, as the existing quoted examples still functioned correctly. The PR has passing CI, an ACK from nervana21, and no dependencies.
