Originally I wanted to use the onload query parameter that is mentioned in googles docs. But I could not get it to work.

I reformatted the code to be more aesthetically pleasing IMO. If you disagree, I'll happily revert any formatting changes!

This PR introduces an optimized approach to load reCAPTCHA.
I was having issues where the recaptcha component would hang indefinitely. I dug into the source code to resolve the issue, and noticed there was no way to tell if the loading of the recaptcha script failed. In addition, the reliance on
setIntervalandsetTimeoutraised concerns for potential race conditions at worst, and poorly optimized code at bets.Guided by Google’s documentation on loading reCAPTCHA, this update focuses on event-driven execution and improved race condition handling. This alignment with Google’s documentation enhances the library’s loading efficiency and aims to give better insight into potential errors.
