It is understandable that you would like to utilize the CHANGELOG and avoid duplicating information in the GitHub release.
I recommend modifying your GitHub releases to include a link to the CHANGELOG.
For example:
https://github.com/adrienverge/yamllint/releases/tag/v1.38.0
it's text would have a link to
https://github.com/adrienverge/yamllint/blob/master/CHANGELOG.rst#1380-2026-01-13
