Avoid temporary file when loading cached Json-LD schema document

[ndr-brt]

Feature Request

Currently to load a cached document for the jsonld service, we copy the file from the classpath to a temporary place:

Connector/extensions/common/json-ld/src/main/java/org/eclipse/edc/jsonld/JsonLdExtension.java

Lines 104 to 117 in 60957b2

	private Result<File> getResourceFile(String name) {
	try (var stream = getClass().getClassLoader().getResourceAsStream(name)) {
	if (stream == null) {
	return Result.failure(format("Cannot find resource %s", name));
	}
	var filename = Path.of(name).getFileName().toString();
	var parts = filename.split("\\.");
	var tempFile = Files.createTempFile(parts[0], "." + parts[1]);
	Files.copy(stream, tempFile, REPLACE_EXISTING);
	return Result.success(tempFile.toFile());
	} catch (Exception e) {
	return Result.failure(format("Cannot read resource %s: ", name));
	}
	}

this could be avoided passing the URI directly

Which Areas Would Be Affected?

This means that in tests going through this code we will fetch a file from an URL?

no, the cache behavior will continue to be the same, but currently (as shown in the code fragment in the issue description) to load the cached document, a temporary file is created, but it is an unnecessary step that could be avoided.
