Preparation to move to sentry-javascript repository

[anonrig]

TODOs

• Remove prettier and related files chore: remove prettier #220
• Remove prettier from eslintrc as well
• Have format and fix keys on package.json fix: change package.json keys #222
• Update tsconfig files depending on monorepo
• Remove package-lock.json since monorepo uses yarn
• Update Github workflows to use latest Ubuntu
• Move jest config and tests test: move tests to dedicated test folder #221
• Remove all eslint dependencies and sync eslintrc with monorepo

When we open PR to sentry-javascript

• drop @typescript-eslint/eslint-plugin and @typescript-eslint/parser - currently fails even though it's a dep of the SDK config package?
