Update .eslintrc.js to remove redundant TS parser and plugin

[wwdrew]

Feature request

Setting the parser and plugin in the template's .eslintrc.js seems redundant as these are already configured in the react-native-community config for *.ts and *.tsx files. Is there a reason it's set this way or can they be removed?

Why it is needed

Trying to simplify the template configuration to make it more compatible with base settings.

Possible implementation

Remove the parser and plugins from .eslintrc.js

Code sample

module.exports = {
  root: true,
  extends: '@react-native-community'
}
