Describe the bug

I have noticed strange results produced by the default help template when my application is using HideHelpCommand:

Using HideHelpCommand in the root command and in a subcommand that has only one command (e.g. program config generate), the output is displayed without "COMMANDS" section.

Using HideHelpCommand in the root only affects subcommands in the sense that "help" command is not shown in "COMMANDS" section, however the "help" command can still be invoked when it is specified as an argument.

To reproduce

I have attached Go playground links in the description.

Observed behavior

See the description.

Expected behavior

HideHelpCommand should hide help command from the usage output as well as disable the command when specified. Ideally, the behavior should be inherited from the parent command.

Additional context

None.
