Infrastructure - Error when pushing theme resources for Keycloak due to the size

The issue is that pushing theme resources to Keycloak fails because the files exceed the allowed size limit. However, it previously worked for the Access Control repository.

remote: GitLab: Your push to this repository would cause it to exceed the size limit of 1,000 MiB so it has been rejected. Please contact your GitLab administrator for more information. To https://gitlab.eclipse.org/eclipse-research-labs/datamite-project/data-support-tools/data_ingestion_and_storage/infrastructure.git ! [remote rejected] develop -> develop (pre-receive hook declined)
