ydb admin cluster config fetch doesn't work on today's main

[blinkov]

I've been trying out #14711 and it didn't work:

ubuntu@static-node-1:~$ /opt/ydb/bin/ydb config profile create default -d /Root/database -e grpcs://$(hostname -f):2135 --ca-file /opt/ydb/certs/ca.crt --user root --password-file ~/password
ubuntu@static-node-1:~$ /opt/ydb/bin/ydb -p default yql -s 'select 1;'

ubuntu@static-node-1:~$ /opt/ydb/bin/ydb -p default admin cluster config fetch
YAML config is absent on this cluster.
ubuntu@static-node-1:~$ head -3 /opt/ydb/cfg/ydbd-config.yaml 
storage_config_generation: 0
static_erasure: mirror-3-dc
host_configs:

Both ydbd and ydb are built from the fresh main branch and it's a new cluster deployed from scratch:

ubuntu@static-node-1:~$ /opt/ydb/bin/ydbd -V

It was a wrong command...
