Fix Docker build: Download libvips tarball to temporary file first

- Modified the Dockerfile to download the libvips tarball to a temporary file (vips.tar.gz) using curl -o, then extract from that file.
- Added 'set -eux' to the RUN command for better debugging output.
- This addresses the 'gzip: stdin: not in gzip format' error by ensuring a complete download before extraction.
