catalog propertie skipTlsVerify true has no effect on java api call when requesting helm repository : certificate is always checked

For storing our helm we use a chartmuseum instance on kube.
We use our own certificates.

Certificates are use for two different thing in onyxia-api.

For helm commands and for JVM with java keystore

We have a secret tls like this one
`kubectl create secret tls onyxia-tls -n $namespace --key $DOMAIN_KEY_FILE --cert $DOMAIN_CERT_FILE`

And we use these values for helm

```

catalogs:
[
{
"id": "chartmuseum",
"name": "Environnements de développement",

1/BEHAVIOR FOR HELM COMMANDS

everything is ok
- when skipTlsVerify is false the file `/etc/ssl/certs/extra/onyxia-tls.cer` is used with helm commands, and it os ok
`/usr/local/bin/helm repo add --ca-file /etc/ssl/certs/extra/onyxia-tls.cer`
- when skipTlsVerify is true helm commands skip certificate verification, and it is ok
`/usr/local/bin/helm repo add --insecure-skip-tls-verify`

2/BEHAVIOR FOR JAVA CODE

There is a problem because if skipTlsVerify false or true, the java code always wants to check the certificate.
- when skipTlsVerify is false the file `/etc/ssl/certs/extra/onyxia-tls.cer` is registered at pod launch with the entrypoint which use keytool and it os ok
- **when skipTlsVerify is true if we do not register certificate at pod launch we have an error because java httpClient always want to check certificate.**

Could you use an httpClient with tls verify deactivated when skipTlsVerify is true ?
