Vuepress: Default viewport settings affect UX badly

[pepelsbey]

By default there’s a viewport configuration that considered an antipattern:

<meta name="viewport" content="width=device-width,initial-scale=1,maximum-scale=1,user-scalable=no">

The maximum-scale=1 and user-scalable=no are locking viewport scaling which affects UX and accessibility badly. See Anti-Pattern: Disabling Pinch-to-Zoom by eBay for details.

I’m ready to send PR removing those viewport options, but I decided to check if you’d agree.

Yeah we can remove them for accessibility.
