fix duplicate screenshot

[yuchan2215]

For example, let's say there are the following functions in the file: ExampleChip and ExampleChipPreview. In the current implementation, ExampleChip is also included in ExampleChipPreview, resulting in the same preview being displayed twice. To avoid this, I added a process to delete duplicate files.

Lines 263 to 280 in fe9d08a

	private suspend fun findImages(
	elements: List<KtElement>,
	files: List<File>
	): List<File> {
	val elementNames = elements.mapNotNull { element ->
	element.name
	}
	return withContext(Dispatchers.Default) {
	elementNames.flatMap { elementName ->
	val pattern = ".*$elementName.*.png"
	files
	.filter {
	val matches = it.name.matches(Regex(pattern))
	matches
	}
	}
	}
	}
