ADAPT-000: Add options to fontSize.js for the modular scale steps

[yvonnetangsu]

READY FOR REVIEW

Summary

• Added steps in fontSize.js utility which correspond to decanter 6's @modular-typography mixin. It purely sets the font size using the modular scale of 1.25 ratio and responsive variants are generated. This allows for eg, su-text-m0 md:su-text-m1 2xl:su-text-m3 (step 0 = 1em for mobile, step 1 = 1.25em for MD, step 3 = 1.95em for 2XL).
