update react scripts dependency (#255)

* Move "dependencies" close to "devDependencies"

Makes it easier to have a quick overview

* Upgrade "react-scripts" to latest version

With new versions of node (> v16) the build scripts fails with the following error "error:0308010C:digital envelope routines::unsupported"

* Upgrade "react-scripts" to v5 - Fix import

* Upgrade "eslint" dependencies

The latest version of "react-scripts" uses eslint v8 causing the following error "... ERROR in Plugin "react" was conflicted between ".eslintrc.js" >> eslint-config-airbnb ..."

* Upgrade "eslint" dependencies - Allow nested components as props

* Upgrade "eslint" dependencies - Fix lint issues
