fix(grid-rs): pull wgrib2 from the Elixir image

Browse source 
wgrib2 isn't in Debian apt on trixie — the main prop Dockerfile builds
it from source in a dedicated stage. Rather than duplicate that 5-min
compile in the Rust image's CI path, copy the already-built
/usr/local/bin/wgrib2 + /usr/local/lib/libg2c.so* out of the published
Elixir image.

Also add the libgfortran5/libaec0/zlib1g/libpng16-16t64/libopenjp2-7
runtime deps that wgrib2 links dynamically against — same set the
Elixir runtime installs.
