Support ESLint v8

[BPScott]

Description

Fixes #300

Updates @shopify/eslint-plugin to support eslint v8.

• Increase peer dependency on eslint from ^7.30.0 to ^8.3.0
• Increase node version to run on CI to 12.22, as that is the minimum version that eslint requires.
• Replace usage of the long-deprecated babel-eslint and eslint-plugin-babel with @babel/eslint-parser and @babel/eslint-plugin.
  • Update babel/* rules to @babel/*
  • Remove babel/camelcase and babel/valid-typeof rules as they do not exist in @babel/eslint-plugin.
  • Update setting parsers from babel-eslint to @babel/eslint-parser
  • Update usage of ClassProperty ast type to also check for PropertyDefinition
• Update versions of all plugins. Note major version bumps to eslint-plugin-jest and typescript-eslint/* and eslint-plugin-prettier which caused the following changes:
• Remove jest/prefer-inline-snapshots rule
• Replace jest/prefer-to-be-null and jest/prefer-to-be-undefined and jest/no-expect-resolves rules with jest/prefer-to-be and jest/no-restricted-matchers
• Rename jest/valid-describe rule to jest/valid-describe-callback
• Rename jest/lowercase-name rule to jest/prefer-lowercase-title

LGTM. Looks like a few dedupe opportunities in the lock file, but all the code makes sense.

Hey @BPScott - is there a possibility of a new release, so we can start using this? 🙏
