Allow import paths to end with an extension in VSCode

[cinderlee]

The "import/extensions": "off" rule was introduced in .eslintrc.json to ignore the eslint error where extensions were missing in the import paths. When initially attempting to add extensions to the end of import paths (such as import AddItem from './components/AddItem.tsx) the VSCode IDE + typescript configuration indicates an error, like the one below.

We should investigate and aim to remove the rule to allow for import paths toe end with an extension in VSCode and other IDEs.
