Update required dependencies (#46678)

jkotas · web-flow · commit f0fad1fb576b · 2025-06-11T16:40:05.000-07:00
* Delete libgdiplus from list of dependencies

libgdiplus was needed by System.Drawning.Common on Unix system. We stopped supporting System.Drawning.Common on Unix starting with .NET 6.

* Delete libunwind from the list of dependencies

We eliminated dependency on libunwind starting with .NET 3.0

 ## Scripted install
 
 The [dotnet-install scripts](../tools/dotnet-install-script.md) are used for automation and non-admin installs of the **SDK** and **Runtime**. You can download the script from <https://dot.net/v1/dotnet-install.sh>. When .NET is installed in this way, you must install the dependencies required by your Linux distribution. Use the links in the [Install .NET on Linux](linux.md) article for your specific Linux distribution.
