Update instrumentation-libraries.md with new Oracle DB support info

[alexkeh]

Oracle added .NET OpenTelemetry support to its managed ODP.NET (for .NET FW) and ODP.NET Core providers that are available on NuGet. I updated the Databases table to reflect this support is available.

Why

Oracle recently added OpenTelemetry support to its two .NET providers. The Databases table needs an update to reflect this support.

Fixes #

What

@alexkeh, we are open to include support for Oracle in AutoInsturmentation.
Please let me know if you have some time to create PR, I will be happy to help.

Hi @Kielek,
Going through my company's internal approval process for the EasyCLA is a big unknown in terms of time and effort. I decided to file an issue instead since the change is straightforward for a README file.
