This PR is some dependency upgrades and clean up. I did my best to upgrade build dependencies such as sass, gulp, and webpack to modern versions. yarn start and yarn build complete with these changes using Node 18 but wanted to do this PR before I try to actually use them in the upstream applications. I also tried to clean up the browser support configurations to drop support for IE. Once this is merged, I'll publish a pre-release version to npm so I can try them in @nycplanning/ember and, ultimately, Zola.
