Include Root Certificates in Custom Trust Store

https://bitwarden.atlassian.net/browse/PM-19601

📔 Objective

I realized in #5609 that if you include a "additional" certificates directory that directory is treated as the ONLY certificates that are valid for remote servers, kinda defeating the name. To fix that we just include the system root CA's in our custom trust store.
