feat: enable standard.site publishing (blog + material) (#108)

Bump the build submodule to the version that publishes standard.site records,
and wire angular-buch.com's publication config into the article-data build.

- build: 0bb1055 -> 775a3d1 (standard.site publisher, blog + material)
- build-article-data.yml: add BSKY_APP_PASSWORD secret + publication env

Publishing is a no-op until the BSKY_APP_PASSWORD repo secret is added.
