I changed newly introduced `ShowAliases` to `InferHelpText` because first one is not completelly correctly
reflects the action performed.

If we have `HelpTex`t specified for alias:
`def alias_version_V: Flag<["-"], "V">, Alias<version>, HelpText<"blah blah">;`
then regardless of `ShowAliases` flag value, this option will be shown. 
Because old logic prints all options with `HelpText` at first place (and I did not change it here).

Probably we can name it `ShowAllAliases` ? With description saying it will trigger rendering all
aliases regardless they have `HelpText` explicitly set or not.
