It seems that fontWeight is not being taken into account

Hey,

In addition to the color variables (#141 ), I'm having some trouble exporting text styles, more specifically fontWeight.
I couldn't make something like this work:

sketch.addTextStyle({
        name: test ,
        textStyle: {
          fontName: "IBM Plex Sans" ,
          fontWeight: 9,
          fontSize:  15 ,
          lineHeight: 24
        },

I noticed from Sketch's API that a value between 0 and 12 would be expected, but even converting "700" to "9" also didn't work.

Context
I have been trying to combine style-dictionary with sketch-constructor for a design system.
I'm making my main Sketch library (with all the components) to read Layer and Text styles from this file generated from the tokens.
This will be very helpful because I have a multi-brand/single-platform (themes) token setup.

I had to specify the font name to be the bold version if that help? i.e. try IBMPlexSans-Bold
