Issue: 

• Navigate to the https://help.liferay.com/hc/en-us/articles/360017896552-LCS-Preconfiguration article
• The "Preconfiguring LCS to Connect Through a Proxy" anchor link in the table of contents has the incorrect markdown.

Requirement:

• Update the markdown to "#preconfiguring-lcs-to-connect-through-a-proxy"

Note:

• I temporarily updated this on Help Center production, but it will need to be updated in Git before the next import.
