### Describe the Feature Request

I'd like an up-to-date storage library to use inside ionic.

### Describe the Use Case

For those who like me are using `@ionic/storage` and `@ionic/storage-angular`, there isn't any good option and those libraries has not been updated for over 3 years.

### Describe Preferred Solution

Updating the following library: https://github.com/ionic-team/ionic-storage

### Describe Alternatives

Building our own (but it seems complex to me)

### Additional Information

_No response_

Start by reviewing the linked ionic-storage repository and the current @ionic/storage and @ionic/storage-angular packages to determine their maintenance status and supported Ionic integrations. Define what an up-to-date storage library should support, then confirm that the requested package updates and compatibility work are complete.
