request: turn night light off for a few minutes

[kiyui]

Checklist:

• I realise this extension extends on the existing GNOME night light feature and can only control the temperature.
• I have gone through the extension settings to check that this feature is available.

Feature Description:

Was just browsing a bit and I came across this issue where someone may want to have the night light turned off just for a few minutes, and possible re-enable it thereafter.
