deprecate dapp test in dappeteer

[BeroBurny]

Deprecate dappeteer testing dapp in favor of using evaluate method.

do you thing we could start writing tests without adding code to test dapp like:

const resultPromise  = testPage.evaluate(async function() {
   //prepare data
   return window.ethereum.sendAsync(
      {
        method,
        params,
        from: accounts[0],
      });
});
await dappteer.signTypedData()
const result = await resultPromise
