V5 Heroes example responsive layout issues

[kohheepeace]

I found some issues at heroes examples
https://getbootstrap.com/docs/5.0/examples/heroes/

📌 Issues

1. Image should be centered or stretched for tablet and mobile

at "Responsive left-aligned hero with image" example

2. Sign Up form is too narrow for mobile

at "Vertically centered hero sign-up form" example

📌 Fixed Codesandbox demo

This is a codesandbox demo URL which fixes these issues.

I only added Bootstrap's classes to fix these issues. (*It measns I didn't add custom css)

1. Image should be centered or stretched for tablet and mobile

2. Sign Up form is too narrow for mobile

Thanks !

Leaving the image as-is, but will fix the sign up form for sure.
