Allow oidc jwt injection in the helm charts

[alexisdondon]

We should allow oidc token injection in the helm charts if values.schema.json specify it to propagate the identity of the user in the container launched.

In order to do that we need to add in OnyxiaValues https://github.com/InseeFrLab/onyxia-web/blob/2bef7775601f421b9fa4be0512ad4310cc780e0c/src/core/ports/OnyxiaApiClient.ts#L154-L210

maybe a new key:

 oidc: { 
        token: string; 
        refreshToken: string; 
     }

we could then use it in values.schema.json with {{oidc.token}} and {{oidc.refreshToken }}
To do that we need to retrieve this values probably here https://github.com/InseeFrLab/onyxia-web/blob/2bef7775601f421b9fa4be0512ad4310cc780e0c/src/core/usecases/launcher.ts#L984
