[Internal] Make import sorting done with prettier instead of ESLint

[TyHil]

Current import sorting, where the import lines at the top of each file are organized into categories then alphabetically, is done with an ESLint plugin. But this isn't really a linting issue, it's more formatting. Using this PR on Jupiter as a guide (UTDNebula/utd-clubs#348), update this project to sort imports with Prettier, our formatter, instead of ESLint.

This is a cross-project issue so making the same changes to Trends, Skedge, Rooms, Notebook, and the main website on a branch in each project is required.
