[spiral/router] Update Route list command for customization route class

[iAvenger01]

Changing the use of an implementation to an interface to implement a custom route

Q	A
Bugfix?	❌
Breaks BC?	✔️
New feature?	❌

I have my own custom route class that inherits from RouteInterface just like the original class from the spiral/router package. However, the command to display routes does not work because it uses an implementation class rather than an interface in the types. This PR is acknowledged to correct this.
