feat: support resolveSnapshotPath option

[9aoy]

Summary

By default, Rstest saves snapshot files in the same directory as the test files, under a __snapshots__ folder.

You can use resolveSnapshotPath to customize this behavior and specify a different location for your snapshot files.

For example, store snapshots next to test files:

import { defineConfig } from '@rstest/core'; export default defineConfig({ resolveSnapshotPath: (testPath, snapshotExtension) => testPath + snapshotExtension, });

Pull Request Overview

This PR adds support for the resolveSnapshotPath configuration option, allowing users to customize where snapshot files are stored. By default, Rstest saves snapshots in a __snapshots__ folder alongside test files, but this option enables alternative storage strategies like placing snapshots directly next to test files.

• Adds resolveSnapshotPath configuration option to customize snapshot file locations
• Updates documentation in both English and Chinese to explain the new option
• Implements the feature with a custom snapshot environment class and RPC integration
