GH_PAGES_URL is converted to all lowercase

[achim-w]

I found that the URL that is later used as the "anchor" in the linkset.json is converted to all lowercase in the GitHub action.

templates/.github/workflows/signposting.yml

Line 23 in 669ea1d

gh_pages_url=$(echo "$gh_pages_url" | tr '[:upper:]' '[:lower:]')

Is there any reason why this is done? Otherwise, I would propose removing this line, as the URL for the GitHub Pages seams to be case-sensitive (at least for the project name), see e.g. the already published Train of Trainers:

• linkset.json of v1.3.0
  • Anchor: https://fair-by-design-methodology.github.io/fair-by-design_tot/latest/ → ❌
  • Fixed case: https://fair-by-design-methodology.github.io/FAIR-by-Design_ToT/latest/ → ✔️
