Do not show URL in boot info when using Puma

Puma has its own configuration file(e.g. `config/puma.rb`).
Can define a port and a URL to bind in the configuration file. Therefore,
on Rails side, can not grasp which URI to bind finally.

Because of that, it may show a URL different from the actually bound
URL, so I think that it is better not to show it.

Fixes #29880
