fix(packagediff): fix packages being built when the path to package start with same structure

[azlam-abdulsalam]

paths are matched with includes rather than checking the directory properly. This can result in packages being built if the directory structure is similar

fixes #1396

Summary generated by Reviewpad on 13 Oct 23 11:41 UTC

This pull request fixes an issue where packages are built incorrectly when the path to the package starts with the same structure. Instead of properly checking the directory, paths were matched using includes, which could result in packages being built even if the directory structure was only similar. The patch modifies the PackageDiffImpl.ts file to properly check the directory structure before building packages. Additionally, a new test case is added in the PackageDiffImpl.test.ts file to verify the fix.
