fix: Vault health check

[SergeyTsaplin]

While migrating from Docker Desktop to Rancher Desktop on macOS, I encountered an issue where container port forwarding to the host machine was taking a long time. This delay caused the health check to fail with the following error:

self=<urllib.request.HTTPHandlerobjectat0x108683a70>http_class=<class'http.client.HTTPConnection'>req=<urllib.request.Requestobjectat0x1087788f0>, http_conn_args= {}
