Fix ESLint config

[csandman]

• Update all ESLint packages, install the proper ones for this project, and update the config so it is no longer broken.
  • Add the eslint-plugin-jsdoc package, as this project uses JSDoc in multiple places with some invalid types.
  • Remove the eslint-plugin-prettier package in favor of eslint-config-prettier because they don't recommend using it.
  • Fix all of the ESLint warnings and errors that popped up as a result of fixing the config.
  • Add the missing json-stable-stringify package
• Add husky and lint-staged to format with prettier and lint the code in a pre-commit hook.
  • Run a prettier format on all files so that the hooks can do their job in the future
• Remove the @types/node-fetch package as this is not a TS project and it serves no purpose(?)
• Change the engines fields in the package.json to allow anything on node@16 and npm@8 because installing the dependencies is a pain otherwise. You can revert this if there is a specific reason for restricting them to these versions.

Ops, I didn't realize you had this marked as Draft. This all looks good to me, thanks!

I fixed the conflicts and added a commit with 2 eslint warning fixes + some non-eslint things I found on the way.

Were you planning to add anything to this PR? I'm happy to merge it whenever you mark it ready for review

@Claudiohbsantos I had actually only drafted this PR to try and resolve the merge conflicts on GitHub (which I failed to do). I ended up making a new branch with all the final changes from a clean branch of the current master, but I also just pushed them here. So yeah, if you want to help me resolve the remaining conflicts then this branch is ready to go!

@csandman This looks great, thanks for taking care of all of the chores here! Yeah, I've been making a couple of changes to master so it was pretty easy to solve the conflicts since I remembered what I changed yesterday. I'm going to go ahead and merge this one in!
