fix(docker): repair held-back deps before installing build tools

The falkordb/falkordb:latest base image is now Debian Trixie-based
and arrives with apt in a state where the t64 ABI deps that git and
build-essential require (libcurl3t64-gnutls, libtinfo6, libc6-dev,
etc.) are held back. apt itself recommends `apt --fix-broken install`.

Running `apt-get install -y -f` between update and the real install
clears the broken state so the install can proceed. Verified locally
against the exact base image digest CI uses
(sha256:aaf67c724bba36b9fb8d43a2671fd57e89c536b971d72b692a63a168c8053ff4).
