The man page namespace is global, so in order to avoid colliding with other man pages named "config.toml" rename ours to be more descriptive. This also helps with discoverability (now tab-completion of 'man containerd<tab>' will return the config man page), as well as making it much cleaner from the perspective of distributions that want to package containerd.
