I keep selecting .NET 6, it keeps redirecting me to 8

### Type of issue

Other (describe below)

### Description

I have code base in .NET 6, so I need to refer to the docs for version 6.

I need to know what the code was written TO. That may be the same between 6 * 8, but I can not compare if I can not see it.

If a particular interface has not changed between 6 & 8, fine! Send me to version 8, BUT TELL ME IT IS THE SAME!
