Lines in mult-line properties starting with whitespace and dash classified as deletions

First of all thanks a lot for creating this nice action! It's a very nice representation of the plan.

I gave it a try today with a case where a resource is added that includes YAML as one of its properties.
It seems that when a line starts with (optional?) whitespace and a dash, like in this case for lists in YAML, the representation in the comment is rendered as deletion although it is just part of the resource property.

Example in created comment:

Same in original plan:

Uh, interesting case, thanks a lot for surfacing! I'll think about how to fix this, I hadn't dealt with plain YAML files in Terraform yet 👀

Here another example where there is an update to a similar property:

• First line wrongly classified as deletion ❌
• Second line correctly classified as deletion ✔️
• Third line correctly classified as addition/creation ✔️

Same excerpt from original plan:

Yup, all boils down to the same issue! It should be possible to reverse-engineer this, the relevant information should be available 👀
