[BUG] FileReader/FileWriter 未关闭 / 没有正确关闭

[Ghost-chu]

FileReader 打开后未关闭：

Ecore/src/main/java/cat/nyaa/ecore/EconomyCoreProvider.java

Line 46 in 6cf99c5

var ecoreData = gson.fromJson(new FileReader(economyCoreInternalDataFile), EcoreDataInternal.class);

FileWrite 关闭不正确：

Ecore/src/main/java/cat/nyaa/ecore/EconomyCoreProvider.java

Lines 77 to 79 in 6cf99c5

	var writer = new FileWriter(economyCoreInternalDataFile);
	gson.toJson(ecoreData, writer);
	writer.close();

使用 try-with-resources 来自动关闭。

try ( FileWriter writer = .... ) {
// do something
}
