Typo noticed in the idThon README file

[Okpainmo]

Hi Polygon Advocates Team,

I am Andrew Okpainmo, and I am currently participating in the idThon challenge.

I am creating this issue to call attention to what I believe to be a typographical error in the idThon README file. The affected words are underlined in the attached screenshot below. I guess this was simply an error.

I believe the correct statement should be "... the understanding of decentralised identity ..." not "... the understating of decentralised Identify ..." as it currently is in the README file.

The typo makes understanding what the challenge is all about to be difficult - especially for first-time visitors who are new to the challenge repo.

I wish to update the README file and create a PR - implementing the correction if I am permitted to. I will be anticipating a reply on this issue permitting me to proceed with that.

Thanks a lot.
