feat(docker/ci): migrate Docker and CI from npm to bun

Docker changes:
- Use oven/bun:1-debian as base image instead of node:20-trixie-slim
- Replace npm ci with bun install --frozen-lockfile
- Replace npm run commands with bun run
- Mount bun.lock instead of package-lock.json
- Update cache paths for Bun's cache directory
- Rename NPM_RUN_PRUNE env var to BUN_RUN_PRUNE

CI workflow changes:
- Update bashlib.sh npm-install function to use bun
- Update superset-frontend.yml to use bun run commands
- Update release.yml to use setup-bun action and changesets
- Update superset-e2e.yml to use setup-bun action
- Update superset-playwright.yml to use setup-bun action
- Update superset-translations.yml to use setup-bun action

Note: superset-embedded-sdk and superset-websocket remain on npm
as they are separate packages with their own lockfiles.
