Add redirect for Pathways Program 

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
```
