Duotone Circle is no longer duotone

[mjsmith037]

Where the duotone circle used to have two layers: an outer circle (primary) with a faded center (secondary), now it is all one faded color on the documentation and apears indistinguishable from the solid version in practice (i.e. --fa-primary-color and --fa-secondary-color appear to not affect appearance).

Hi!

Thanks for being part of the Font Awesome Community and thanks for reporting this.

I can confirm that the icon changed from 5.10.0 to 5.10.1, but I don't know if this is an intended change or not

@sensibleworld could you please take a look?
