Show path to vulnerable dependency in dependency list - Documentation

Main Issue - #227620 (closed)

Problem to solve

Show path to vulnerable dependency in dependency list is not documented.

Implementation plan

• Document dependency path feature at https://docs.gitlab.com/ee/user/application_security/dependency_list @djadmin
• Make sure Dependency Scanning documentation doesn't need to be updated @fcatteau
  • We may have to document for which package managers this feature is supported. See supported package managers.

Note

The feature is being built with feature flag - #241739 (closed)
