Auto merge of #25308 - atouchet:win10, r=jdm

Use Windows 10 instead of 7 in user agent string

<!-- Please describe your changes on the following line: -->
I tried testing https://my.panomoments.com/ in the latest nightly version of Servo but it wouldn't load because it requires Windows 8 or newer and Servo's user agent string says it's using Windows 7. This change should allow sites requiring a modern version of Windows to run. This could potentially cause issues for users running older versions of Windows however. A better long term solution would be to do #18194.
