Capacitor v5 compatibility in 3.4.x

[piotr-cz]

Version 3.4.0-rc.0 includes commit cdeb575 which changed text in the readme from Capacitor 5 to Capacitor 6.

This suggest that package requires Capacitor v6, however this version works fine with Capacitor v5 and dependencies still use @capacitor/* packages at the ^5 version.

I think that:

• changes in readme from cdeb575 should be rolled back until peerDependencies have "@capacitor/core": "^5.0.0 || ^6.0.0"
• when above is changed, readme should state that this package is compatible with both Capacitor v5 and v6
