feat: per-assertion snapshot path template in config

[dgozman]

Introduces the following properties in the config that take precedence over config.snapshotPathTemplate.

export default {
  expect: {
    toHaveScreenshot: {
      pathTemplate: '__screenshots__{/projectName}/{testFilePath}/{arg}{ext}',
    },
    toMatchAriaSnapshot: {
      pathTemplate: '__snapshots__/{testFilePath}/{arg}{ext}',
    },
  },
};

Additionally, changes the default template for aria snapshots to:

{snapshotDir}/{testFileDir}/{testFileName}-snapshots/{arg}{ext}

This is technically a breaking change.

Fixes #34483.
