add parsed font-weight value to highlight-overlay card

[IgorKurkov]

Hi everyone!

I suggest adding the font-weight value (bold, thin, 400, 500, 900) to the highlight-overlay card if available in styles. something like this: It will help us to see immediately the font-weight inline without additional clicks to get the Computed-styles tab.
