Pull request overview

This PR removes a misplaced alarm control panel test from the text component's trigger tests. The removed test (test_alarm_control_panel_triggers_gated_by_labs_flag) was testing alarm control panel triggers with parameters like "alarm_control_panel.armed", which is unrelated to text entities. This appears to be a leftover from copy-pasting test files during initial setup.

Key Changes

• Removed the test_alarm_control_panel_triggers_gated_by_labs_flag test function and its parametrization from tests/components/text/test_trigger.py
• The identical test already exists in the correct location: tests/components/alarm_control_panel/test_trigger.py
