Baixar Keyguard 2.1.0 per a Windows

This update introduces initial support for creating new password credentials on Android via Android Credential framework.
[!NOTE]
A large part of the release is testing the updated new release pipeline that maintains the release log for Flathub. The updated pipeline should provide users with a list of versions and the changelog summary for each of them. The summary is auto-generated by an LLM from full changelog as a part of the release pipeline. I hope to extend it at some point to other stores that support displaying changelogs.
I've also turned on GitHub's immutable releases.
