Subject: [PATCH] fix: keep docs images on tags and stop unappliable digest
 pins

Turn off digest pinning for every image in cplieger/docs. Its examples
are copied verbatim into the guide pages, and the docs/*.md manager can
move a tag but not write a digest, so a pinned bump made the example and
its copy differ and failed the snippet check on main.

Turn off digest pinning for the docs/*.md manager everywhere. Its pin
updates can never be applied, so the pin-dependencies branch errored on
every run in cplieger/docs, docker-fclones-scheduler,
docker-rsync-scheduler and tautulli-remap.

Each compose file under examples/ is shown verbatim inside a docs/*.md page, and scripts/snippets.py --check fails when the two differ. config:best-practices pins digests (docker:pinDigests), but the docs/*.md custom manager below has no digest group, so a bump wrote `traefik:v3.7.14@sha256:...` into the example and `traefik:v3.7.14` into the page and turned main red (docs#9). Tags are also what a reader should copy: the images guide recommends a tag that keeps updating and treats a digest as an opt-in the reader's own Renovate maintains. tests/ follows suit because the Examples workflow deliberately runs the current :latest app images and upstreams; a digest there would only add a bump PR per upstream rebuild. A later packageRule wins, so this overrides the preset's digest pinning.",
