Make a single ConnectWalletButton export in ui-kit package

[abhishek-01k]

Currently there are two exports: <ConnectPushWalletButton /> and <TogglePushWalletButton account={account} />

Make them inside a single component only

<PushWalletButton
  account={account} // null is non-login state
  component=’button’ | component // needs to be button or custom component
  title=’title’ // this is the title displayed in the button
  styling=’styles’ // this is again taken if the styles of the button is not incorporated
>

Note: IFrame should be injected as part of that component, if design issues then move iFrame to provider or implementation part if it always will come
