Hello everyone !

I have this issue when i start Kibana. I saw different solution on linux but not on windows and I work on windows

```auto
Failed to fetch latest version of synthetics from registry: Error connecting to package registry: request to https://epr.elastic.co/search?package=synthetics&prerelease=true&kibana.version=8.11.1 failed, reason: self-signed certificate in certificate chain

```

This is my kibana config :

```auto
# This section was automatically generated during setup.
elasticsearch.hosts: ["https://localhost:9200"]
elasticsearch.serviceAccountToken: "XXXXXXXXXXXXXXXXXXXXX"
elasticsearch.ssl.certificateAuthorities: ['C:\Users\Gabin\Documents\Suite ELK\kibana-8.11.1\data\ca_1701857.crt']
elasticsearch.ssl.verificationMode: full
xpack.encryptedSavedObjects.encryptionKey: XXXXXXXXXXXXX
xpack.fleet.outputs: [{id: fleet-default-output, name: default, is_default: true, is_default_monitoring: true, type: elasticsearch, hosts: ['https://10.222.54.65:9200'], ca_trusted_fingerprint: XXXXXXXXXXXXXXXXXX}]

```

Best regards
