* Fix misleading descriptions on lyric.set_hold_time action
While on Honeywell Lyric thermostats the user can set a "Hold Until" time of day, the set_hold_time action does define a time period instead (Example: 01:00:00)
Therefore both descriptions are incorrectly using "until" for explaining the purpose of the action itself and the `time_period` field.
This commit re-words both and adds some additional context that helps users (and translators) better understand this action and its purpose.
In addition the action name is changed to proper sentence-casing.
* Replace "time" with "duration" for additional clarity
