Add from_secret support for secrets:

They currently still depend on environment:: https://woodpecker-plugins.geekdocs.de/plugins/wp-docker-buildx/#wp-docker-buildxdata-secrets

Might be a tricky one without environment:. I guess this requires a new setting secrets_env or similar which explicitly injects WP secrets which is then only used by secrets?

Yeah that's the way to go 👍
