Clarify documentation for git/scm resources `user` attribute

[matthewhively]

chef-web-docs/data/infra/resources/git.yaml

Lines 202 to 207 in 7ec349e

	- property: user
	ruby_type: String, Integer
	required: false
	default_value: "`HOME` environment variable of the user running chef-client"
	description_list:
	- markdown: The system user that will own the checked-out code.

Please clarify whether the git command actually executes as the listed user, or whether it simply CHMODs the files after the fact?

See CHEF-11172

Is that supposed to be a link somewhere?

@matthewhively Sorry, I meant that as a reference to an internal issue.
