chore: update to image-spec v1.1.1 (#909)

Wwwsylvia · web-flow · commit 853e0125ccad · 2025-03-04T17:30:13.000+08:00
1. Use the media type regex defined in [`image-spec v1.1.1`](https://github.com/opencontainers/image-spec/blob/v1.1.1/schema/defs-descriptor.json#L7) in `pack.go` 2. Update the doc links to reference `image-spec v1.1.1` and `distribution-spec v1.1.1` Resolves: #910 Signed-off-by: Lixia (Sylvia) Lei <lixlei@microsoft.com>
