🎨 Set up linting and formatting (#2120)
* ⬆️ Upgrade TS to 4.3.5

* 👕 Add ESLint configs

* 🎨 Add Prettier config

* 📦 Add deps and commands

*  Adjust global .editorconfig to new ruleset

* 🔥 Remove unneeded local .editorconfig

* 📦 Update deps in editor-ui

* 🔨 Limit Prettier to only TS files

*  Add recommended VSCode extensions

* 👕 Fix build

* 🔥 Remove Vue setting from global config

*  Disable prefer-default-export per feedback

* ✏️ Add forgotten divider

* 👕 Disable no-plusplus

* 👕 Disable class-methods-use-this

* ✏️ Alphabetize overrides

* 👕 Add one-var consecutive override

*  Revert one-var consecutive override

This reverts commit b9252cf935.

* 🎨 👕 Lint and format workflow package (#2121)

* 🎨 Format /workflow package

* 👕 Lint /workflow package

* 🎨 Re-format /workflow package

* 👕 Re-lint /workflow package

* ✏️ Fix typo

*  Consolidate if-checks

* 🔥 Remove prefer-default-export exceptions

* 🔥 Remove no-plusplus exceptions

* 🔥 Remove class-methods-use-this exceptions

* 🎨 👕 Lint and format node-dev package (#2122)

* 👕 Fix build

* 🔥 Remove prefer-default-export exceptions

*  Update exceptions in ActiveExecutions

* 🔥 Remove no-plusplus exceptions

* 🔥 Remove class-methods-use-this exceptions

* 👕 fix lint issues

* 🔧 use package specific linter, remove tslint command

* 🔨 resolve build issue, sync dependencies

* 🔧 change lint command
