Release notes for 2.3.0

This is the first version with support for Manifest version 3, which means that some background processes have been changed and some adjustments had to be made on the server side.

As a result of these changes, the browser's own HTTP cache is now used instead of a separate cache and the HTTP queries have been reduced in size, which has significantly increased efficiency.

- Use of Service Workers instead of background scrips
- Added and corrected some flags like Rainbow and Pride, Antarctica, Curaçao, Guernsey, Isle of Man, Jersey, Libya, Sint Maarten, South Sudan and United Nations
- Implement Secret, X-UUID, RelayDynamicPathResponse and RelayLocallyUsedResolvedIP for company policies (show internal domain data, custom flags and detect to which IP a domain resolves for your users) - - Only available if a DomainFlag Relay Service is used using Group Policies
- Cache duration is set by server to dynamically reduce load
- Individual requests which significantly accelerate queries (time until flag is displayed)
- Added link to search IP and ASN in popup (not only domain)
- Add support for Persian - Thanks to @OnlyMilad
