Pull request overview

This PR adds comprehensive documentation and examples for integrating mc-router with autoscaling capabilities. The autoscaling feature allows Minecraft servers to automatically start when players connect and stop after periods of inactivity, saving resources when servers are idle.

• Added two Docker Compose example files for mc-router autoscaling (verbose and minimal versions)
• Created new autoscaling documentation page comparing mc-router, Lazymc, and Lazytainer solutions
• Updated the examples documentation to include mc-router autoscaling section

The Source links point to the external mc-router repository, but the examples are now part of this repository at examples/mc-router-autoscale/. The links should point to the local examples to be consistent with other examples in this file (e.g., line 28 and 187). The Source link should point to https://github.com/itzg/docker-minecraft-server/blob/master/examples/mc-router-autoscale/compose-minimal.yml and the detailed example should point to https://github.com/itzg/docker-minecraft-server/blob/master/examples/mc-router-autoscale/compose.yml.
