Ignore Casing for route parameters in Minimal APIs

[rafikiassumani-msft]

Describe the bug

When the route parameters do not match due to casing, Minimal APIs throws an exception. We would like either to ignore casing and stay consistent with other other attributes.

To Reproduce

   app.MapGet("/user/{FirstName}/{lastName}", ([FromRoute()]string? firstName, [FromRoute()]string lastName) => 
    UserService.GetUser(firstName, lastName, "aa"));

Exceptions (if any)

Error message (Notice FirstName != firstName):

System.InvalidOperationException: 'firstName is not a route paramter.'
