Not a bug per se, but I noticed some things about the templating doc that I thought could use a polish:

• The YAML in the template functions section contains a lot of parameters that could be removed in order to bring focus to the relevant portions
• The advanced templating document title contains "configuration policy", which isn't entirely accurate since some sections apply to Policy
• The hub/managed cluster templating comparison table has a separate "policy metadata" row that can be consolidated with the context variable row.
