feat(vue): Apply stateTransformer to attachments in Pinia Plugin

[s1gr1d]

Continuation of #14474

As the store logic changed a bit, I changed the PR a bit. The getAllStores function can now receive the stateTransformer and apply it.

Closes #14441

m: The default options need to be destructured into the options object so that people can provide only a few of the options but still get the rest of the defaults.

// declare the type with no optional fields
type SentryPiniaPluginOptions = {
  attachPiniaState: boolean;
  addBreadcrumbs: boolean;
  actionTransformer: (action: string) => any;
  stateTransformer: (state: Record<string, unknown>) => any;
};

const DEFAULT_PINIA_PLUGIN_OPTIONS: SentryPiniaPluginOptions = {
  attachPiniaState: true,
  addBreadcrumbs: true,
  actionTransformer: action => action,
  stateTransformer: state => state,
}

// make sure user options are `Partial<SentryPiniaPluginOptions>` so that they can define
// a subset of options they want to override.
export const createSentryPiniaPlugin: = (userOptions: Partial<SentryPiniaPluginOptions> = {}): PiniaPlugin => {
  const { attachPiniaState, addBreadcrumbs, actionTransformer, stateTransformer } = { ...userOptions, ...DEFAULT_PINIA_PLUGIN_OPTIONS } as SentryPiniaPluginOptions;

This also means we don't need to pass in stateTransformer into getAllStoreStates, because it can grab it from the closure.

I know that stateTransformer could be grabbed from the closure here but I made it an argument of the function so it's more explicit that a stateTransformer is used when calling getAllStates. Otherwise it would be a weird side effect you only see when looking at the function code.

But good catch with the destructuring - right now it's either the users' object or the default one.
