Pod request access landing page using Constraints validation APIs

Hello everyone 👋,

Here's my solution for Pod request access landing page.

In this solution, I am using the Constraints validation APIs to validate the email address field. I am also using patternMismatch over typeMismatch for stricter email formats since the default typeMismatch also accepts email addresses without a top-level domain, i.e. x@y is a valid email address.

Any feedback and suggestions on how I can improve are very welcome! Thanks and happy coding! 🙇‍♂️🙏
