Fix artifact upload path pattern in CI

- Change from specific path to wildcard pattern to ensure files are found
- Upload: dist/BTCPayServer.Plugins.Breez/**/*.btcpay -> dist/**/*.btcpay
- Release: plugin/BTCPayServer.Plugins.Breez/**/*.btcpay -> plugin/**/*.btcpay
- This ensures the .btcpay files are captured regardless of version subdirectory structure
