Add prettier code formatter

[thelovekesh]

Summary

This PR aims to add prettier as the code formatter.

• Add prettier and @wordpress/prettier-config devDeps.
• Update @wordpress/eslint-plugin config from @wordpress/eslint-plugin/recommended-with-formatting to @wordpress/eslint-plugin/recommended as it incorporates prettier by default.
• Update code formatting with a new formatter.
• Update eslint-disable and translators comments(It is done because prettier and ESLint use different JS parsers, hence prettier was showing errors at how those eslint-disable comments were placed.).
• Remove Eslint rule(react/jsx-one-expression-per-line) due to conflict with prettier.
• Move .eslintrc to .eslintrc.js as it is recommended to use an extension-based config file.

As opposed to applying prettier, I thought we were just going to disable prettier from running to avoid making many changes? I mean, I don't think it's necessarily a problem to update the formatting since I don't think there are significant PRs that would be made stale by applying prettier. I don't feel strongly either way. Just curious.

Ahh. Maybe I misinterpreted our discussion. I think I can add prettier 😄

I don't think there are significant PRs that would be made stale by applying prettier.

I also considered the case and I think having a code formatter like prettier is not a bad choice. Prettier is a very widely used tool and can be helpful in developer experience which is useful in the long run if someone wanted to work with JS codebase.

We can disable it as well. I am aware of disabling it in VSCode using a config file but not sure about other code editors/IDEs.

Note: we'll need to Squash-merge this and then add the commit hash to a .git-blame-ignore-revs file.
