Do not fail on partial trust warning.

[mitchdenny]

This PR fixes an issue that was reported where the underlying shell out to dotnet dev-certs to trust a certificate might result in a non-zero exit code where the cert is partially trusted.

In these circumstances we probably want to "let it slide" and continue starting up the apphost because there are lots of corner cases around certificate trust particularly on Linux distros which might result in this issue.

Rather than hard blocking we detect we are in this partial trust situation and just display a warning (mostly to help our own diagnostics if it later doesn't actually work).

We should consider modifying dev-certs to return a different exit code for this partial trust situation.

Pull Request Overview

This PR addresses an issue where the HTTPS developer certificate might be partially trusted, preventing a hard failure on a non-zero exit code from the dotnet dev-certs command. The changes include new tests to verify both the success and failure paths and an update to CertificateService to detect and warn when a partial trust condition is encountered.
