Merge bitcoin/bitcoin#28505: rpc: bumpfee, improve doc for 'reduce_output' arg
b3db8c9d5ccfe5c31341169fa7ac044427122921 rpc: bumpfee, improve doc for 'reduce_output' arg (furszy)
Pull request description:
Fixes #28180. Resulted from discussions with S3RK, achow101, and Murch.
The current argument name and description are dangerous as it don't
describe the case where the user selects the recipient output as the
change address. This one could end up been increased by the inputs
minus outputs remainder. Which, when `bumpfee` adds new inputs
to the transaction, leads the process to send more coins to the
recipient. Which is not what the user would expect from a
'reduce_output' param naming.
