style: fix hidden input opactiy

[antuneslv]

When the OTP input is focused, the base input, which should be hidden, is faintly visible. If you zoom in, you can notice it. I'm not sure if it was intentional to set the opacity to 0.01, but I fixed it by setting the opacity to 0 so that the input doesn't appear at all.

Hi, @antuneslv . Thank you for yet another contribution. However, as I remember correctly, with 0 opacity one of the platforms (Android I guess) was failing to display the context menu. Can u please try to "paste" some code through context menu on both platforms, to be sure that nothing is breaking?

Hi @anday013 , unfortunately I don't have an iOS device to test... 😞 However, I did test it on Android, and the context menu works perfectly:

@antuneslv I mean this menu :) When you hold, or double click on the input

This menu also works on Android. :)

Hi @anday013, I'm not sure if you're still waiting for an iOS test, but as I mentioned, unfortunately, I don't have a way to test on that platform. If you need to close the PR because of this, I completely understand.

Hi @antuneslv , I have a chance to test on iOS, I'll handle that. The only thing is that I am on vacation right now, so I apologize for the delays :)

Tested works fine! Thanks!
