test-doc failed to add alternative version links

[targos]

Just saw this in my console output:

make -s test-doc
Failed to add alternative version links to policy
Failed to add alternative version links to report

[Trott]

This will happen if policy.md or report.md have <!--introduced_in=REPLACEME--> instead of something like <!--introduced_in=v11.7.0--> or if they lack an introduced_in at all.

This is a harmless warning in the case of REPLACEME. You should not see those warnings on release tags, but they're fine on master.

For policy, this was fixed in 641de82.

For report, this is still an issue as introduced_in does not appear in report.md. But you will only see it if you force it to build (for example by removing out/doc/api/report.* before running make -s test-doc).

A PR to add introduced_in for report.md should be opened, if it hasn't already been opened. The entire report.md could probably use a review by one or more folks on @nodejs/documentation.
