bug: PPResume got black title bar on mobiles which looks ugly

[xiaohanyu]

Description

PPResume PWA right now has a black title bar on desktop and mobiles, while on desktops is looks OK, however, on mobiles it looks quite ugly.

To fix this from bottom up, we need to enable PPResume PWA respect dark mode #52, however, before we support dark mode, let's just make title bar (theme_color in manifest) the same as in <HeroSection>.

To Reproduce

Install and open PPResume PWA on Android or iOS, and then you will get a black title bar because we set "theme_color": "#202020" in manifest.
