1.19.0

Update to Microsoft.Graph 4.8.0, Microsoft.Graph.Beta 4.18.0-preview, Microsoft.IdentityModel 6.14, and MSAL.NET 4.37.0.

New Features:

A new assembly, Microsoft.IdentityModel.Validators, is now leveraged in Microsoft.Identity.Web as the AadIssuerValidator. It provides an issuer validator for the Microsoft identity platform (AAD and AAD B2C), working for single and multi-tenant applications and v1 and v2 token types. See Identity.Model and #1487. The MicrosoftIdentityIssuerValidatorFactory is still in Microsoft.Identity.Web and leverages this new Identity.Model library

Microsoft.Identity.Web now supports authentication handlers other than JwtBearer, and the token acquisition in web API understands a higher level abstraction of SecurityToken, not only JwtSecurityToken . See #1498.

Bug Fixes:

Make Certificate in CertificateDescription.cs protected internal. See #1484.
