possible memleak in internal CertificateManager

[leeriorio]

In results of static analyze of aspnetcore sources with Svace static analyzer I was found error of cathegory HANDLE_LEAK with message

new X509Certificate2(certificatePath, password, X509KeyStorageFlags.Exportable | X509KeyStorageFlags.EphemeralKeySet) is not disposed at the end of the function

This error was found in internal method ImportCertificate

aspnetcore/src/Shared/CertificateGeneration/CertificateManager.cs

Line 420 in 6ae3ea3

certificate = new X509Certificate2(certificatePath, password, X509KeyStorageFlags.Exportable | X509KeyStorageFlags.EphemeralKeySet);

I see, that there working with created certificate takes specific paths that include platform point, and in variable certificate it can be stored new certificate object.

aspnetcore/src/Shared/CertificateGeneration/CertificateManager.cs

Line 449 in 6ae3ea3

SaveCertificate(certificate);

But at all, how about to add correct disposing of object?
Maybe call of SaveCertificate method should be like:

using var _ = SaveCertifiicate(certificate);
