Documentation of function mosquitto_string_option on mosquitto.h wrongly contains MOSQ_OPT_TLS_KPASS_SHA1 instead of MOSQ_OPT_TLS_ENGINE_KPASS_SHA1

On master branch of mosquitto project (up to commit 15292b2 ), under include/mosquitto.h, the documentation of the function mosquitto_string_option wrongly says a valid value for the 'enum mosq_opt_t option' argument is MOSQ_OPT_TLS_KPASS_SHA1, but should be MOSQ_OPT_TLS_ENGINE_KPASS_SHA1. It is missing a 'ENGINE_' in the option name.

I was not much sure if should be reported as bug.

Noticed the same on the published documentation mosquitto.org doc
