Add feedback link icon in Techdocs Reader that directs to GitLab or GitHub repo issue page with pre-filled title and source link. For link to appear, requires repo_url and edit_uri to be filled in mkdocs.yml, as per https://www.mkdocs.org/user-guide/configuration. An edit_uri will need to be specified for self-hosted GitLab/GitHub instances with a different host name. To identify issue URL format as GitHub or GitLab, the host name of source in repo_url is checked if it contains gitlab or github. Alternately this is determined by matching to host values from integrations in app-config.yaml.
