support latest version of Sentry

[SogoGolf]

Because sentry_flutter >=6.0.0 <6.1.0-alpha.1 depends on sentry ^6.0.0 and sentry_flutter >=6.1.0-alpha.1 depends on sentry ^6.1.0-alpha.1, sentry_flutter >=6.0.0 requires sentry ^6.0.0. And because sentry_lumberdash >=3.1.0 depends on sentry ^5.0.0, sentry_lumberdash >=3.1.0 is incompatible with sentry_flutter >=6.0.0.

So, because sogogolf depends on both sentry_flutter ^6.0.0 and sentry_lumberdash ^3.1.0, version solving failed.
pub get failed (1; So, because sogogolf depends on both sentry_flutter ^6.0.0 and sentry_lumberdash ^3.1.0, version solving failed.)
