Examples rendering broken since 003d8ea

[salim-b]

https://github.com/r-lib/pkgdown/pull/2629 introduced a regression resulting in failed rendering of the pkg reference. I narrowed the issue down to https://github.com/r-lib/pkgdown/commit/003d8ea72aa978ce0357a15c32edf4d84cf08f7e via bisecting.

Reproduce

1. Install pkgdown@003d8ea via remotes::install_github("r-lib/pkgdown", ref = "003d8ea72aa978ce0357a15c32edf4d84cf08f7e")
2. Render the current main branch's pkgdown site via pkgdown::build_site().

Hmmm, it works for me. Do you have the latest evaluate?

[salim-b]

Do you have the latest evaluate?

Ah, that was the culprit!

I'm using the P3M CRAN mirror, and evaluate v0.24.0 has only become available there after the usual delay, so I was still on 0.23.0 when filing this issue. Updating resolved it, thanks!
