YANG Configuration.md fix table of contents links (sonic-net#21072)

Why I did it
Due to excess whitespace, the table of contents does not render as links in github, leading to navigation issues.

This might cause some minor "pain" for other merge requests due to the formatting differences in the ToC, but it should really only take a second to correct. Better to fix it once and make everyone's life easier than just living with it.

Work item tracking
How I did it
Updated whitespace and a couple other very minor correctness changes for MarkDown. There are still other changes I'd like to do but much lower priority and possibly not worth the disturbance.

How to verify it
View the corrected table of contents here:

Compared to original unrendered ToC here:

Which release branch to backport (provide reason below if selected)
Not needed
