Google Photos: missing photoslibrary.sharing OAuth scope blocks share-album action

## Description

The `share-album` action (`components/google_photos/actions/share-album/share-album.mjs`) calls `POST /v1/albums/{albumId}:share`, which requires the `https://www.googleapis.com/auth/photoslibrary.sharing` OAuth scope.

However, the current Pipedream OAuth app for Google Photos only requests these scopes:
- `email`
- `profile`
- `photoslibrary.readonly.appcreateddata`
- `photoslibrary.edit.appcreateddata`
- `photoslibrary.appendonly`

The missing `photoslibrary.sharing` scope causes a 403 "insufficient scopes" error when trying to share an album.

## Note on Google deprecation

Google announced deprecation of `photoslibrary.sharing` (along with `photoslibrary.readonly` and `photoslibrary`) after March 31, 2025. If this scope is no longer available, the `share-album` action should be deprecated or removed.

## Impact

5 out of 6 Google Photos actions work correctly. Only `share-album` is affected.

## Workaround

Users can configure a custom OAuth client ("Bring Your Own OAuth") with the sharing scope included.
