Lib: Test help output with FR localeHEADmaster

Check that translation and the `ReaderT` really do work by changing
localisation of the STDOUT "help" output from `EN` to `FR`.

To actually test this, add a french translation of the `GitHubCommit`
plugin description. This string is successfully output by the "help"
plugin.
