chore: upgrade to prettier v2 + enforce import types (#21013)Co-authored-by: Satish Gandham <hello@satishgandham.com> Co-authored-by: Satish Gandham <satish.iitg@gmail.com> ## Description This PR upgrades Prettier to v2 + enforces TypeScript’s [`import type`](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-8.html#type-only-imports-and-export) syntax where applicable. It’s submitted as a separate PR so we can merge it easily. As a part of this PR, we reformat the codebase heavily: - add `import type` everywhere where it’s required, and - re-format the code to account for Prettier 2’s breaking changes: https://prettier.io/blog/2020/03/21/2.0.0.html#breaking-changes This PR is submitted against `release` to make sure all new code by team members will adhere to new formatting standards, and we’ll have fewer conflicts when merging `bundle-optimizations` into `release`. (I’ll merge `release` back into `bundle-optimizations` once this PR is merged.) ### Why is this needed? This PR is needed because, for the Lodash optimization from https://github.com/appsmithorg/appsmith/commit/7cbb12af886621256224be0c93e6a465dd710ad3, we need to use `import type`. Otherwise, `babel-plugin-lodash` complains that `LoDashStatic` is not a lodash function. However, just using `import type` in the current codebase will give you this: <img width="962" alt="Screenshot 2023-03-08 at 17 45 59" src="https://user-images.githubusercontent.com/2953267/223775744-407afa0c-e8b9-44a1-90f9-b879348da57f.png"> That’s because Prettier 1 can’t parse `import type` at all. To parse it, we need to upgrade to Prettier 2. ### Why enforce `import type`? Apart from just enabling `import type` support, this PR enforces specifying `import type` everywhere it’s needed. (Developers will get immediate TypeScript and ESLint errors when they forget to do so.) I’m doing this because I believe `import type` improves DX and makes refactorings easier. Let’s say you had a few imports like below. Can you tell which of these imports will increase the bundle size? (Tip: it’s not all of them!) ```ts // app/client/src/workers/Linting/utils.ts import { Position } from "codemirror"; import { LintError as JSHintError, LintOptions } from "jshint"; import { get, isEmpty, isNumber, keys, last, set } from "lodash"; ``` It’s pretty hard, right? What about now? ```ts // app/client/src/workers/Linting/utils.ts import type { Position } from "codemirror"; import type { LintError as JSHintError, LintOptions } from "jshint"; import { get, isEmpty, isNumber, keys, last, set } from "lodash"; ``` Now, it’s clear that only `lodash` will be bundled. This helps developers to see which imports are problematic, but it _also_ helps with refactorings. Now, if you want to see where `codemirror` is bundled, you can just grep for `import \{.*\} from "codemirror"` – and you won’t get any type-only imports. This also helps (some) bundlers. Upon transpiling, TypeScript erases type-only imports completely. In some environment (not ours), this makes the bundle smaller, as the bundler doesn’t need to bundle type-only imports anymore. ## Type of change - Chore (housekeeping or task changes that don't impact user perception) ## How Has This Been Tested?
