ESLint improvements (#388)

## Description

Adds various features to improve the DX with eslint:

### Webpack

- Use `eslint-webpack-plugin` for better observability of lint errors
during development.

### Ignored files

- Enable `.gitignore` support for eslint.

### Commit hook

- Add `eslint --fix` to pre-commit hook.

### Github actions
- Add eslint check to a new github action workflow.
- Use `eslint-formatter-gha` to annotate PR files with lint failures
(see the Files changed tab,
[example](https://github.com/openfrontio/OpenFrontIO/pull/388/commits/73862230be5aad7b18e122b1cd4ab05fc9570b2c)).
