[Text Component] expo prop will not be enough

[RobinCsl]

In #239, I thought the problem would be solved entirely.

However, if we are using Text inside Button component within universal-components, then expo prop will be false by default. That means that Button component used in Expo will not show bold text as bold.

Discussing with @JoseDuSV, we believe that universal-components should read some configuration file and/or figure out if it's an Expo environment or not.

Expo detection will be probably cleanest solution. But I'm not sure if there is some feature that will allow us to accurately detect it. 🤔
