fix: extract mdpress binary to /tmp to avoid overwriting repo files

The mdpress release tarball includes README.md and other docs alongside
the binary. Extracting in the repo directory overwrites the book's own
README.md, causing mdPress documentation to appear in the generated PDF.

Fix by downloading and extracting to /tmp, then moving only the binary.
