feat(react-native-razorpay): add config plugin for UPI Intent support on iOS

[gerzonc]

Why

Related issue: #379

But basically, by following React Native Razorpay docs we can see that in order to use the UPI Intent on iOS we must add the apps URL scheme's to LSApplicationQueriesSchemes.

How

We must pass values to the LSApplicationQueriesSchemes on Info.plist, more specifically, an array of values, to tell which apps our app is going to communicate with (e.g. tez, phonepe and paytmmp).

Test Plan

1. Follow the instructions to install the lib on your app.
2. Add the following to your plugins attribute on your app.json (or app.config.ts):

   plugins: [
   [
     "react-native-razorpay",
     { paymentApps: ["tez", "phonepe", "paytmmp"] },
   ],
   ]

Alternatively, could just document that the user must add schemes to the Info.plist directly:

{
  "expo": {
    "ios": {
      "infoPlist": {
        "LSApplicationQueriesSchemes": [...]
      }
    }
  }
}

and avoid the config plugin altogether. Another possible solution could be something simple like this:

module.exports = function (config, schemes) => {
  if (!config.ios) config.ios = {}
  if (!config.ios.infoPlist) config.ios.infoPlist = {}
  if (!Array.isArray(config.ios.infoPlist.LSApplicationQueriesSchemes)) {
    config.ios.infoPlist.LSApplicationQueriesSchemes = []
  }
  config.ios.infoPlist.LSApplicationQueriesSchemes = [...(new Set([
    ...config.ios.infoPlist.LSApplicationQueriesSchemes,
    ...schemes
  ])];
}

    config.ios.infoPlist.LSApplicationQueriesSchemes = []
  }
  config.ios.infoPlist.LSApplicationQueriesSchemes = [...(new Set([
    ...config.ios.infoPlist.LSApplicationQueriesSchemes,
    ...schemes
  ])];
}

Ooh, didn't know we could modify Info.plist directly from app.json 😲 I believe there is no need for this config plugin then!
