Proposal: Add heavier weight of Noto Serif to the mix

[iamthomasbishop]

Problem

As part of a recent issue, we found our current selection of font-weights is somewhat limiting in some cases inside the editors (Aztec + Gutenberg) – in particular when bold text is the starting point and we want to display a heavier weight for the sake of making a change visible. We currently can't do this with the current options of normal and bold, so for the time being we are using CSS to add weight (and a slight bit of letter-spacing to account) to visualize this for the time being.

Proposal

I'm proposing that we add a heavier weight – either semi-bold or black.

The caveat is that only normal and bold weights are available straight from the source (Google Fonts). However, I have found additional weights are available from other sources:

• Adobe Fonts: https://fonts.adobe.com/fonts/noto-serif
• Font Squirrel: https://www.fontsquirrel.com/fonts/noto-serif?q%5Bterm%5D=noto&q%5Bsearch_check%5D=Y

Questions/thoughts:

• How much effort is required in adding an additional font-weight?

• How are we currently bundling/including fonts in Gutenberg?

• This change would probably also apply to Aztec. Would it make more sense to add the font-weight to the apps instead of Gutenberg?

@iamthomasbishop do we still need this?

@SergioEstevao It is worth doing an investigation into how we can/should include other weights, but I don't know how easy it will be. If it's difficult or impossible, we can close this ticket.
