Release notes are always absent of build system changes

## Describe the bug
I've noticed with how release notes are now being handled they basically never contain information that pertains to changes in the buildsystems/dependencies.

I prime offender would be https://github.com/elementary/wallpapers/releases/tag/5.5.0, which Meson build system support was added and there's no mention of this. This is particularly frusterating for me as a distro maintainer, changes in the build system or dependencies are often the most important information.

I do understand this is performed in a more automated way, so it would be nice if this information could be included again. Otherwise I actually have to manually read the git log for this information on the relevant files.

Thanks. worldofpeace :sparkles:
