🐛 Bug: prettier-plugin-sentences-per-line - Indentation is not preserved for list items that span multiple lines

### Bug Report Checklist - [x] I have tried restarting my IDE and the issue persists. - [x] I have pulled the latest `main` branch of the repository. - [x] I have [searched for related issues](https://github.com/JoshuaKGoldberg/sentences-per-line/issues?q=is%3Aissue) and found none that matched my issue. ### Expected Consider the following `md` snippet with a list item. ```text - `Array<string>` - to specify an array of top-level package properties to lint sorting on only those properties. All properties not in this collection will be sorted by "sort-package-json" specifications. ``` List items containing multiple phrases across multiple lines should maintain consistent indentation. ### Actual At the moment the second line indentation is stripped producing the following output: ```text - `Array<string>` - to specify an array of top-level package properties to lint sorting on only those properties. All properties not in this collection will be sorted by "sort-package-json" specifications. ``` Removing `prettier-plugin-sentences-per-line` proceeds the expected behaviour. ### Additional Info - Coming from https://github.com/JoshuaKGoldberg/eslint-plugin-package-json/pull/1500#issuecomment-3708203854 `md` complete snippet can be found here: https://github.com/JoshuaKGoldberg/eslint-plugin-package-json/blob/eeff2b8af576e503a155b72313ac9e69807c48c2/docs/rules/order-properties.md?plain=1#L56-L57
