Fix the problem of deleting/renaming on the win platform

[binsee]

When deleting or renaming files on the win platform, the nodes cannot be operated correctly.

The way of handling file names in parseFile() was changed before, but the same process is not performed when deleting and renaming files.

Reference

markdown-links/src/parsing.ts

Lines 35 to 36 in 1e09056

	export const parseFile = async (graph: Graph, filePath: string) => {
	filePath = path.normalize(filePath);

Therefore, the node that should be removed still exists.

Thank you so much!
