Update zip archive append example

[madelson]

I think this example should leverage ZipArchiveMode.Create because it is only appending/writing to entries. Create is more efficient in that scenario since it does not have to buffer the entire archive in memory. Furthermore, it is confusing that ZipArchiveMode.Create supports appending (unlike File.Create / FileMode.Create), so calling this nuance out in the first code example seems prudent.

See dotnet/runtime#49149
