the link

https://www.ibm.com/us-en/marketplace/spectrum-mpi

redirects to

Find a product (https://www.ibm.com/us-en/products)

the rest of the pull just deals with ordinary redirects

.github/dependabot.yml

didn't bother to deal with this

the link https://docs.github.com/github/administering-a-repository/configuration-options-for-dependency-updates redirects to https://docs.github.com/en/code-security/dependabot/dependabot-version-updates/configuration-options-for-the-dependabot.yml-file
