What to-do when your contribution to public project is not counted

[kurenchuksergey]

Hi, two weeks ago I contributed spring-amqp repository through fork-pull (it is merged to the main branch)
Today I checked the release, which contains my commit, but for some reason, I am not mentioned as a contributor

Seems my email was correctly set because on my profile commit counted.
Commit with my email: https://github.com/spring-projects/spring-amqp/commit/3620f11ebb773dc9bd0c7bce2e447164d4955cbe.patch
Release with my commit: https://github.com/spring-projects/spring-amqp/releases/tag/v3.1.0-RC1

At the same moment the API answer contains my contribution:

QUESTION:
Is it a bug or my mistake somewhere?
