fix(build): pass BUN_VERSION build-arg (canary tags were built from latest)

[ImBIOS]

Bug: build_updated.sh never passes --build-arg BUN_VERSION, so the Dockerfile's ARG BUN_VERSION=latest default is used for every build. All canary-* tags (e.g. canary-24.19.0-slim) are therefore identical to latest-* images — bun 1.3.14 — instead of the canary channel.

Fix: pass --build-arg BUN_VERSION=$bun_version. Canary versions (containing -canary) map to the floating canary GitHub release tag, since pinned canary releases (e.g. bun-v1.3.13-canary.20260425.1) are not published on GitHub (404).

Verified: https://github.com/oven-sh/bun/releases/download/canary/bun-linux-x64-baseline.zip → 206 (exists); pinned canary URL → 404.
