(GH-192) Update troubleshooting for v1.1

[michaeltlombardi]

PR Summary

Prior to this change, the troubleshooting documentation for DSC v1.1 only listed the dsccore provider for retrieving the DSC process ID, not the dsctimer provider.

This change:

• Updates the code example to include a filter for both providers.
• Cleans up grammar, style, and formatting.
• Resolves #192
