Gary Larizza 03fa4eaaa2 docs: Helm Values test updates 
* Convert all files with.period.separators to hyphen-separators.
* Rename and markdown_test.go to be specific to Helm Values.
* Move helm-values_test.go to be in the same directory as the Helm Values doc.
* Move Blackbox common configuration CUE file to `config/prometheus` so it can be imported as necessary.
* Use explicit import statements for Blackbox common config in `blackbox` and `prometheus` components.

Closes: #399
