…Net.EncryptWeMust

The library we use for LetsEncrypt invokes 'ConfigureHttpsDefaults' at https://github.com/ffMathy/FluffySpoon.AspNet.EncryptWeMust/blob/6f6ac68cad178abadb5838edc8b29274d72d3519/src/FluffySpoon.AspNet.EncryptWeMust/KestrelOptionsSetup.cs#L22-L25
Also see <https://learn.microsoft.com/en-us/aspnet/core/fundamentals/servers/kestrel/endpoints?view=aspnetcore-8.0>
An excerpt from the documentation from Microsoft:
> Calling ConfigureHttpsDefaults multiple times replaces prior Action instances with the last Action specified.
