fix: update detection of changelog links

[richardlau]

The Node.js CHANGELOG.md file was changed so that _ characters in
links are now escaped.

Refs: nodejs/node#40322

---

Note that we'll need to update again after nodejs/node#40475 but for now this needs to work against the current v16.x-staging branch.

I put HTML comments in the README to remind people (including myself) of tooling that needs to be updated if the format of certain parts change. Maybe we can/should do that for CHANGELOG too?

Sounds reasonable.
