Enhance SignupForm with Debounced Validation

[Jatin24062005]

Fixes #issue-3235

Changes:
Debounced Username & Email Validation: Ensures API calls are made only after 300ms of inactivity, reducing the frequency of requests during typing.
adding a debounce method which make any function or promise delay as per the require time and than applied these to async function for it.

Thanks so much for your work on this!

I think this feels pretty good so far—the only changes I'd make are to remove the comments and to add back in the aria-label property for the input field. Let me know if you have any questions or further thoughts on this!

Everything is good to go now.

Thanks for the update on this!

Just wanted to clarify that my earlier note to remove the comments was referring to all of ones within the file, not just the one that was pinpointed. Although I feel that it might be best to remove them, if you'd like we can keep the ones here within this file. In general, I think we should only include comments as an additional note or to provide further context that might not be easy to tell when looking through a file. Down to discuss this further though if you have any other thoughts on this!

I'm so sorry, I'm updating this note (which previous said this was approved) because I got confused with another one of your PRs 😭 For this one, I wanted to add that although you did add back in one of the aria properties, there's still a few that are missing from the file. I'll pinpoint the ones that need to be added back in!

Sorry again for the confusion!

Sorry I accidentally confused this with another one of your pull requests!

Sorry again about the confusion!

I added in the additional places where the aria attributes should be added back in. Thanks again and let me know if you have any questions!

@raclim First of all, that was funny! Also, I agree with you. Give me a sec—I'm removing all the unnecessary comments now.

[Jatin24062005]

@raclim now Can you please review it again without any confusion : )

Thanks so much for your understanding and for the quick update!

I added in one last aria-hidden label that was missing, but otherwise I think this feels good to me! Thanks so much again for your work on this!
