Fix for Issue 511: ShapeCastHit has no details on ShapeCastStatus::Converged

[kirilllysenko]

This is a PR with suggested bug fix in issue #511. The fix seems also logical when looking at documentation for field details of ShapeCastHit class:

/// The result of a shape cast.
#[derive(Copy, Clone, Debug, PartialEq)]
pub struct ShapeCastHit {
    /// The time at which the objects touch.
    pub time_of_impact: Real,
    /// Detail about the impact points.
    ///
    /// `None` if `status` is `PenetratingOrWithinTargetDist` and
    /// [`ShapeCastOptions::compute_impact_geometry_on_penetration`] was `false`.
    pub details: Option<ShapeCastHitDetails>,
    /// The way the time-of-impact computation algorithm terminated.
    pub status: ShapeCastStatus,
}

@Vrixyz Thank you for approving! I see tests failing and they are definitely not failing because of my changes. Does it require actions from my side?

@kirilllysenko CI fails are indeed not related, as you merged master in I think they'll pass now, thanks!

After consideration, the correct condition is a bit more involved, see https://github.com/dimforge/bevy_rapier/pull/521/files#r1639994370

It's especially useful to read through ShapeCastStatus doc to understand different cases.
