Add redirect for Pathways Program

[jules32]

Add a redirect so that this link: https://openscapes.org/pathways-to-open-science

Redirects to https://openscapes.github.io/pathways-to-open-science/.

To do this, I believe it means adding this to the netlify.toml file following this pattern:

[[redirects]]
  from = "https://openscapes.github.io/pathways-to-open-science/"
  to = "/pathways-to-open-science"
  status = 301

merged this PR #92, but I did not push a rendered version of a page. I don't know/understand whether that's necessary

Still getting Page Not Found from https://openscapes.org/pathways-to-open-science; not sure if this takes time to be implemented?
