Expected result
See playground link-- should warn because outer fragments are pointless since there is only one child. Moreover, the vscode plugin should auto-remove these.
eslint's react/jsx-no-useless-fragment
output:
Fragments should contain more than one child - otherwise, there’s no need for a Fragment at all
