Replace dotnet/reverse-proxy images to dotnet/yarp

[benjaminpetit]

Hi,

Since the yarp project migrated from microsoft/reverse-proxy to dotnet/yarp, we want to reflect this image change in the container. The new container image name should be dotnet/yarp.

We only shipped a preview version in the nightly branch.

Steps needed:

• [ ] Add a new entry for the new images in https://github.com/microsoft/mcr (https://github.com/microsoft/mcr/pull/3848)
• [ ] Rename the existing doc and docker container in this repo to dotnet/yarp (https://github.com/dotnet/dotnet-docker/pull/6215)
• [ ] Update docs links to reflect the github change (https://github.com/dotnet/dotnet-docker/pull/6215)

To be confirmed (if possible to do):

• [ ] De-list dotnet/reverse-proxy in mcr so it doesn't show up on the portal (https://github.com/microsoft/mcr/pull/3848)
