fix(local.ini): straggling s/couch_httpd_auth/chttpd_auth/

[jaydoane]

Overview

The appropriately named hack_local_ini function in dev/run lives up
to its name by adding a random secret to the end of whichever
section contains the line "; require_valid_user = false\n".

Recent commits updated the setup application from
couch_httpd_auth to chttpd_auth without also changing this line
in local.ini, which had the fun effect of causing setup to fail with
this error:

[notice] 2021-10-30T18:50:15.019530Z node1@127.0.0.1 <0.817.0> 85d0421b9c 127.0.0.1:15984 127.0.0.1 adm POST /_cluster_setup 500 ok 12

This change "fixes" dev/run by also updating the straggling section
name in local.ini.

Testing recommendations

Running e.g.

dev/run -a adm:pass --no-eval 'dev/remsh'

should result in a formed cluster and a remsh on node1 instead of a crash:

[ * ] Running cluster setup ... failed: b'{"error":"setup_error","reason":"Cluster setup unable to sync admin passwords"}\n'
