Properly remove log_print

[The-Compiler]

This is a follow up to 3f82006 which didn't
make it clear that log_print is also removed in the changelog and didn't remove
it from the reference docs.

Closes #7612

Good catch, thanks!

Something broke on CI:

Merging as the CI failure is unrelated and already being tracked in #7616.

Thanks @The-Compiler!
