docs: add link to official yocto quick guide

[Ruadhri17]

Proposed changes

Host requirements can change with different Yocto release or when using different host OS. To make sure user can be more up-to-date with Yocto changes, I added link to official Yocto quick guide.

Types of changes

• Bugfix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Improvement (general improvements like code refactoring that doesn't explicitly fix a bug or add any new functionality)
• Documentation Update (if none of the other choices apply)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)

Paste Link to the issue

• Setup yocto build machine #2766

I don't think this statement goes far enough to highlight the importance of matching the yocto version that is supported by the meta-tedge-projects. The rewording won't be trivial, but I'll give it a shot soon.
