add eslintrc.json for windows machine

if I just clone and start, I see a lot of prettier error due to the CRLF thing, need to add this to the eslintrc.json file(well if there are other ones in the future, that prettier/prettier block

{
"extends": [
"react-app",
"prettier"
],
"plugins": [
"prettier"
],
"rules": {
"prettier/prettier": [
"error",
{
"endOfLine": "auto"
}
]
}
}
