Out-of-the-box fonts not rendering correctly

[iSilkline]

Before you start - checklist

• I followed instructions in documentation written for my React-PDF version
• I have checked if this bug is not already reported
• I have checked if an issue is not listed in Known issues
• If I have a problem with PDF rendering, I checked if my PDF renders properly in PDF.js demo

Description

I've been using the built-in the Helvetica and Helvetica-Bold out-of-the-box font families for some time and everything worked great.

I recently updated my react-pdf package and it seems that support for out-of-the-box fonts is broken. I first noticed because bold text (Helvetica-Bold) is rendering as normal weight. I went to test Courier and Courier-Bold and they both rendered as Helvetica. I then tried Times-Roman and Times-Bold... everything is still rendering as normal Helvetica.

Steps to reproduce

Create pdf with any of the out-of-the-box font families.

Expected behavior

Using fontFamily "Helvetica" should render as Helvetica with normal font weight. Using fontFamily "Helvetica-Bold" should render as Helvetica with bold (700) font weight.

Actual behavior

Everything renders as Helvetica with normal font weight.
