I don't have a means of testing this, it's just a guess based on some of the Github actions for pushing pages, e.g.

https://github.com/peaceiris/actions-gh-pages/blob/0b7567fde6f7517edcc13d8ffa2d89cd8734d47c/src/set-tokens.ts#L100

@xperiandri Release pipeline is not tried after this commit, was it fixed. Can you queue a release build to test it?

The github pages part seems to be working ok now (the pages at https://fake.build are showing the version as 6.1.0 and have the updated release notes)
