Add font family, size and weight to the `.docs-primary-btn`. This guarantees that applying the class to non-button elements, like anchors, will results in the same visual representation.
To increase the ease of development we are moving @angular/docs into the adev directory within this repo. While
we are doing this to improve our development experience in the short term, efforts are also in place
to maintain a division between this @angular/docs (shared) code and adev itself, so that it can be extracted
back out in the future when components is ready to leverage it as well.
