Updated boolean for non-deletion cases in SyncManager determineSyncActions method

[esmodea]

I put together this fix, it has to do with this Issue: #37

here is some context:
Description
When I change any file in the vault it syncs properly but then after it syncs if I don't change that file before next sync it undoes my sync. I've been trying to use this plugin for a small team of devs so we can utilize the Kanban plugin Obsidian has and I can confirm two different machines, one on MacOS and one on Windows 11, have this problem.

Steps to reproduce

1. Sync a notes file
2. Change the notes file
3. Sync the notes file
4. Sync the notes file again
5. See unchanged notes file

I looked into it and it seems that in the file src/sync-manager.ts there's an if-else statement on line 729 that only checks if the localSHA !== localFile.sha. I believe it would be more accurate to also check remoteFile.lastModified < localFile.lastModified, as well as adding an else-if to the latter block to ensure that localSHA == localFile.sha && remoteFile.lastModified > localFile.lastModified evaluates to true before downloading the file.

Original code

if (localSHA !== localFile.sha) {
  actions.push({ type: "upload", filePath: filePath });
  return;
} else {
  actions.push({ type: "download", filePath: filePath });
  return;
}

My (somewhat) tested & modified code

if (localSHA !== localFile.sha && remoteFile.lastModified < localFile.lastModified) {
  actions.push({ type: "upload", filePath: filePath });
  return;
} else if(localSHA == localFile.sha && remoteFile.lastModified > localFile.lastModified) {
  actions.push({ type: "download", filePath: filePath });
  return;
}

Not sure if I'm just running the wrong node version or if the type errors are related to new updates to node packages but I also fixed those, can revert those changes if necessary.
