Remove trailing space from string in const.py

[marazmarci]

The Validate with hassfest workflow is constantly failing since Sep 26th with the following error message:

[TRANSLATIONS] Invalid translations/en.json: the string should not contain leading or trailing spaces for dictionary value @ data['options']['step']['init']['data']['adapt_only_on_bare_turn_on']. Got 'adapt_only_on_bare_turn_on: When turning lights on initially. If set to `true`, AL adapts only if `light.turn_on` is invoked without specifying color or brightness. ❌🌈 This e.g., prevents adaptation when activating a scene. If `false`, AL adapts regardless of the presence of color or brightness in the initial `service_data`. Needs `take_over_control` enabled. 🕵️ '

The error message is the same ever since for every other failed workflow run.

My small change aims to fix the issue, hopefully making the workflow succeed.
