chore(eslint-config): update eslint to 8

[gribnoysup]

I'm updating eslint to 8

Opening as draft before I go on vacation so I don't forget the state of it

• Remove eslint-config-mongodb-js completely
  Somehow we still had a few packages with this one in dependencies
• Update eslint to 8
  I'm not updating to 9 right away to reduce the blast radius there seems to be enough issues caused by this update already that would be nice to deal with before we're forced to adapt for the new config format on top of this
• Update relevant eslint pugins that we depend on to latest
  Those are 8/9 compat so we can go straight to latest with them
• Adjust rules when needed
  Some configurable eslint rules that we have changed the schema a bit, adjusted that
• Deal with new issues reported:
  • Better detection of @typescript-eslint/no-explicit-any
  • New recommended @typescript-eslint/prefer-promise-reject-errors
  • @typescript-eslint/no-var-requires renamed to @typescript-eslint/no-require-imports
  • New recommended @typescript-eslint/no-base-to-string
  • New recommended no-unsafe-optional-chaining
  • Catch with unused err now shows up as an error
  • New recommended @typescript-eslint/no-redundant-type-constituents
  • New recommended @typescript-eslint/no-duplicate-type-constituents
  • Better detection of @typescript-eslint/unbound-method
  • New recommended @typescript-eslint/no-unsafe-declaration-merging
  • Better detection of @typescript-eslint/no-unused-expressions
  • New recommended @typescript-eslint/only-throw-error
  • New recommended @typescript-eslint/no-unsafe-enum-comparison
  • Better detection of @typescript-eslint/no-misused-promises
