Is your feature request related to a problem? Please describe:
I upgraded my project capacitor v6 to v7. Getting the below error when running 'npm install'

npm error Could not resolve dependency:
npm error peer @capacitor/core@"^6.0.0" from @capacitor-community/photoviewer@4.0.1
npm error node_modules/@capacitor-community/photoviewer
npm error   @capacitor-community/photoviewer@"^4.0.1" from the root project

Describe the solution you'd like:
Can you please support your plugin to Capacitor v7
