Either make config required in Documentable::To::HTML::Wrapper or add reasonable defaults

[JJ]

The config file is actually required only in these two lines:

https://github.com/perl6/Documentable/blob/334637080b6488f4972712fb86d3f173d9a5d982/lib/Documentable/To/HTML/Wrapper.pm6#L42-L43

We need either to add reasonable defaults for both, or make it required

Required here:

Documentable/lib/Documentable/Config.pm6

Lines 34 to 41 in 3346370

	die X::Documentable::Config::InvalidConfig.new(:msg("'title-page' entry missing"))
	unless %!config<title-page>;
	die X::Documentable::Config::InvalidConfig.new(:msg("'pod-root-path' entry missing"))
	unless %!config<pod-root-path>;
	$!title-page = %!config<title-page>;
	$!pod-root-path = %!config<pod-root-path>;

Anyway, they have been removed from the wrapper as attributes.
