chore: convert JSDoc comments to TSDoc

[dsanders11]

Most of the "conversion" here is simply deleting @param and @returns which are only types, since they're redundant to the TS types, sometimes wrong, and TSDoc doesn't include types for obvious reasons.

eslint-plugin-tsdoc is disabled in test files due to usage of @jest-environment in some files, and it's unlikely there are going to be TSDoc comments in those files anyway.
