maint: clear dependency warnings

Clears out most of the dependency warnings (mainly unmet peer dependency
warnings) by adding or updating various dependencies. Still seeing two
warnings that can only be fixed by updating to the latest hardhat. See
discussion in #2260 for more context about our attempts to upgrade to
the latest version of hardhat.
