chore: upgrade @mongodb-js/zstd from 2.0.0 to 2.0.1

[rlinehan]

The CodeQL github action was failing on other prs and on main with:

npm error code 127
npm error path /home/runner/work/client-sdk-javascript/client-sdk-javascript/packages/client-sdk-nodejs-compression-zstd/node_modules/@mongodb-js/zstd
npm error command failed
npm error command sh -c prebuild-install --runtime napi || npm run clean-install
npm error > @mongodb-js/zstd@2.0.0 clean-install
npm error > npm run install-zstd && npm run compile
npm error
npm error
npm error > @mongodb-js/zstd@2.0.0 install-zstd
npm error > bash etc/install-zstd.sh
npm error prebuild-install warn This package does not support N-API version undefined
npm error prebuild-install warn install No prebuilt binaries found (target=undefined runtime=napi arch=x64 libc= platform=linux)
npm error bash: etc/install-zstd.sh: No such file or directory

claude suggested that 2.0.0 has a broken fallback install that references a missing etc/install-zstd.sh script, causing npm ci to fail in CI environments where no prebuilt binary is available. This seems to have fixed the issue.
