Is your feature request related to a problem? Please describe.
As it turns out, IBM has supported an official nuget package since 2020 - but it doesn't appear near the top of nuget search results for "db2". If you go to https://community.ibm.com/community/user/blogs/vishwa-hs1/2020/07/12/db2-net-packages-download-and-configure, you will see that they have support, which means our lib\DB2 folder can go away!

Describe the solution you'd like

1. Delete lib\DB2 folder
2. Support https://www.nuget.org/packages/Net.IBM.Data.Db2/9.0.0.300

Additional context

1. This is a breaking change.
2. This will resolve the C# compiler warning MSB3270:
   There was a mismatch between the processor architecture of the project being built "MSIL" and the processor architecture of the reference "IBM.Data.DB2", "AMD64". This mismatch may cause runtime failures. Please consider changing the targeted processor architecture of your project through the Configuration Manager so as to align the processor architectures between your project and references, or take a dependency on references with a processor architecture that matches the targeted processor architecture of your project.

Is this a feature you'd like to submit a PR for?
