ci: match workflow name instead of filename in artifact filter (#229)

## Summary

Publishing with craft fails because the artifact filter key in
`.craft.yml` used the workflow **filename** (`ci.yml`) instead of the
workflow **name** (`CI`).

Craft's `GitHubArtifactProvider.filterWorkflowRuns()` matches config
keys against the workflow run's `name` field, not the filename. The
filter `ci.yml` becomes regex `/^ci\.yml$/` which never matches `"CI"`,
causing all workflow runs to be filtered out and artifact retrieval to
fail after 3 retries.

## Changes

- Rename the CI workflow from `CI` to `Build` (better describes its
purpose)
- Update `.craft.yml` artifact filter key to `Build` to match the
workflow name
