Dear Maintainer,

I'd like to ask for a new release of shtool on Debian, including the
multi-arch line in debian/control.

The hint appears in tracker.debian.org, and has already been committed
to salsa.debian.org around 2 years ago, but was never released.

That line not being there prevents php8.4-dev (and older versions, which
also depend on shtool) to be installed using the foreign architecture on
multi-arch systems - I verified it with php8.4-dev:arm64 on an amd64 system.
