[enchantment] `inline` should be `statement` not literal

[alexander-akait]

Need fix it, not high priority

[ichiriac]

Can you add a sample code in order to understand a use case

[alexander-akait]

@ichiriac we extends Inline node from Literal node and Literal from Expression node, but Inline should be extends from Statement node, just internal fix

@evilebottnawi - do you want to change the used node, or just change inheritance ? If it may introduce breaking changes, it should be released in 3.0.0 ?
