Typescript config parity with Browsertrix repo (#289)

Follow-up from #288 

This matches the strictness rules with the Browsertrix repo,
specifically `noImplicitAny`, and then adds `// @ts-expect-error`s to
suppress existing errors this change raises. This'll help us keep code
quality high moving forward.

Going to just directly merge this once it passes CI; as with #288, this
doesn't change any code, just comments.
