We cannot add new parameters in the middle, since we accept parameters by JSON
array as well as by dicts. In fact, this broke tests, but due to unrelated
breakage in the GitHub "Automerge" functionality, it got applied as
556e38c838 ("askrene-bias-channel: bias call add
up.").
Also add tests, and a better Changelog line.

Changelog-Added: JSON-RPC: `askrene-bias-channel` now has a `relative` option to add, rather than replace, a channel bias.
Any file in this directory which is executable and whose name only
consists of alphanumeric characters, space, '.', '-' or '_' will be
automatically loaded when lightningd starts (unless suppressed with
commandline options).
