docs: fix broken Docker Hub link for the alpine image

[anjeongkyun]

The alpine link on the image registry rate limiting page points to https://hub.docker.com/r/_/alpine, which returns a 404. Official images on Docker Hub are served under /_/<name>, so the working URL is https://hub.docker.com/_/alpine.

This updates the single occurrence in docs/supported_docker_environment/image_registry_rate_limiting.md.

Poem

A bunny spots a broken trail,
And fixes the Alpine link without fail.
Docker paths now point just right,
Clear and current, neat and bright.
Hop, hop—docs are good tonight!
