Updates icons to use Remixicons where they don't already (#1157)

* Swapping the icons on the Browse by Topics (and elsewhere since this is a shared component) and on Departments List

* Swapping out the rest of the icons that were marked

* Removing a bunch of SVG icons that we don't need anymore (they're all Remixicons now)

* forgot one

* swapping out last few icons

* Swapping icon on Learning Resource Card

* Figured these two out so swapping - these may need to change though

* Explicitly adding a data-testid to the grab handles on the card templates

The Mui icons seem to do that by default but the Remixicons don't so the test was failing.

* switching some more icons

* some more remixicon replacements

* adding remixicon as dependency

* fixing icon

* replacing external link icon

* fixing visual issue

* swapping out more remixicons

* updating yarn locklfile

* updating package json

* making some more replacements

* replacing some more icons

* replacing more icons

* fixing size

* replacing storybook references to mui

* removing material icon package

* removing final refs to mui icon
