SDK Installation on RHEL Should Rely on DNF Over YUM

[nagilson]

Describe the bug.

Users may see Unable to get latest .NET Installation Data: Please update the .NET Install Tool to version 2.0.2 or later." after clicking the button 'Install .NET SDK' in VS Code from DevKit in RHEL 9.5.

This is why it is failing:
rhel-9-for-x86_64-baseos-rhui-rpms': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried when we try to use yum.

In recent RHEL versions, DNF should be preferred over Yum.

Please attach log file(s) here if you have any.

The log file location should be copied to your clipboard if you came from VS Code.
