をみたら、

Current Plan
Personal, 1 person
Includes the Docker essentials and is ideal for individual developers, education, open source communities, and small businesses.
Cost: $0
Docker Desktop
Unlimited public repositories
Docker Engine + Kubernetes
Limited image pulls per day
Unlimited scoped tokens

制限は１日あたりのpullであって、pushじゃないんじゃないのだろうか。

他に原因があるかもしれず、調査中。
