ci(TestingData): Update IPFS configuration

Steps:

1. Rsync updates to the DataLad repository

  # DataLad repository
  # https://github.com/InsightSoftwareConsortium/itk-wasm-testing-data
  cd ~/data/itk-wasm-testing-data
  rsync -rvt ~/src/itk-wasm/build-emscripten/ExternalData/ ./
  datalad save
  datalad push --to github

2. Export for upload to IPFS

  datalad export-archive /tmp/itk-wasm-testing-data.tar.gz
  cd /tmp
  tar xvzf itk-wasm-testing-data.tar.gz
  cd itk-wasm-testing-data
  w3 put . -n itk-wasm-testing-data-v1.0.0-b.18 -H --no-wrap

3. Pin the CID on Pinata

4. Pin the CID on estuary.tech
