Add replace-build-vars composite action, wire into docker.yaml

Browse Source 
Replaces {{BUILD_VAR_*}} placeholders in all text files of the calling
repo's checkout with Gitea Actions build/commit/branch info before the
docker build step runs. Language-agnostic (plain text substitution),
runs unconditionally, no-op when no placeholders are present.

name: Replace Build Placeholders
description: >
Ersetzt {{BUILD_VAR_*}}-Platzhalter in allen Textdateien durch Gitea-Actions-Build-Infos
(Commit, Branch, Run-Metadaten, …). Sprachunabhängig (reiner Text-Replace,
kein Build-Tool-Bezug), kein Input nötig.
