CommandError: duplicate key value violates unique constraint "core_signingservice_name_key"

[git-hyagi]

Version
Tested with quay.io/pulp/galaxy-minimal:stable.

Describe the bug
When a signing service is already stored in the database, every new pulp-api container (galaxy-minimal image) will output the error:

CommandError: duplicate key value violates unique constraint "core_signingservice_name_key"
DETAIL:  Key (name)=(ansible-default) already exists.
pulp [None]: pulpcore.deprecation:WARNING: verify_signature() is deprecated and will be removed in pulpcore==3.25; use gpg_verify().
CommandError: duplicate key value violates unique constraint "core_signingservice_name_key"
DETAIL:  Key (name)=(container-default) already exists.

Additional context
Even though these errors do not interfere with the app execution they slow down the container startup.

If we remove this functionality from the script, it will address both.
