docs deploy: exclude docs/ from sdist + pin compose project name

The Astro docs site doesn't belong in the published sdist (node_modules,
build artefacts, dev container scaffolding). Adds `docs/` to the existing
sdist exclude list, alongside the other dev-only paths.

Compose project name pinned to `mcaxl-docs` via the v2 `name:` field.
Without it, Compose defaults to the parent directory's basename — and
all three sibling docs sites live in `docs/`, so they were colliding
and cross-recreating each other on every `up`.
