These changes look good to me, thank you for taking this on! :) Just two very minor comments -- up to you if you want to address those and I am happy to approve as-is.

Minor: This makes sense to log when we are setting the value for CertificatePath after retrieving the certificate from the CODEQL_PROXY_ var, but maybe not here.

Perhaps, we should just log when it is set instead - just to avoid that it happens silently (then we always know whether it happens or not).

| * Proxy and certificate environment variables are now set for the subprocess that invokes the NuGet CLI, enabling it to access private registries during this part of the workflow. |

Minor: Change "Proxy" to "Private registry proxy" to disambiguate from ordinary proxies that may be configured on a system. Alternatively, since "private registries" are already mentioned in the last part of the note, restructure the sentence to emphasise that part. For example:
| * Proxy and certificate environment variables are now set for the subprocess that invokes the NuGet CLI, enabling it to access private registries during this part of the workflow. | |
| * The subprocess for the NuGet CLI is now provided with the proxy and certificate environment variables needed to access private registries if any are configured. |
In this PR, we set the proxy and certificate environment variables when invoking the NuGet CLI for restoring packages found in
packages.configfiles.Furthermore, we also log the executed NuGet command, similar to what we do when invoking the
dotnetCLI.
