Update dotnet dependency wording for CCM Website

[imm0rtalsupp0rt]

Description Of Changes

I have fixed a typo in the docs regarding the codebase lock for CCM, as well as made the changes to the requirements and codeblock to mention and run the installation of the latest dotnet dependencies, respectively, including a date declaration to allow users to know there may eventually be later versions available.

Motivation and Context

It was brought to my attention that while the requirements and codeblock were brought up-to-date with the CCM shift to .NET 8.0, the blurb about the codebase being locked still said 6.X.X. The dotnet dependencies listed in the requirements and codeblock were also outdated.
