Bump ESLint ecmaVersion to 2022

[Gazook89]

Your idea:

Right now our .eslintrc.js config file is set to use ecma version 2021, and I'd like to bump it to 2022. Here is a link that briefly describes some changes: https://dev.to/jasmin/whats-new-in-es2022-1de6

In particular, I like the d regex flag for matching indices. It is used in editor.jsx line 155 right now. Because it is not in ECMA 2021, it throws a lint error, but it works in the browser.

Any objection? Or want to go further, to ECMA 2023? Or we can set the config to use lastest. I don't have any need for anything beyond 2022 (except 2024 may include Temporal when it comes out).

This looks to be resolved by the current config?

If the linter isn't throwing an error anymore we can close this.
