build: update Flatpak JBR to 21.0.10 and refresh app metadata

- Switch JetBrains Runtime (JBR) from the JCEF variant to the plain version (v21.0.10) since the app does not use embedded Chromium.
- Update JBR download URLs and SHA-256 hashes for both x86_64 and aarch64 architectures.
- Update screenshot URLs in the Flatpak metainfo to point to the new repository location and include high-quality JPG assets.
- Add new screenshots showcasing repository details, RPM installation, and AppImage support on Linux.
- Update the homepage URL in the metainfo to reflect the current repository owner.
