[BPK-1153] Downgrade @storybook/react-native to fix issue

[shaundon]

The issue
When using storybook actions (or indeed any addons), we're getting an issue where triggering the action causes an error to appear.

The error message itself links to this page, which in turn links to this issue.

The solution
I tried all sorts of different changes to the code but I couldn't get it to work. In the end, through trial and error I figured out that downgrading @storybook/react-native by one patch version (3.2.17 ➡️ 3.2.16) sorts it out.

It's not an ideal long term solution, but it does fix things for now.

3.3.0 of Storybook is currently in alpha, I intend to next find out if that fixes the issue, and also find out what exactly changed from 3.2.16 to 3.2.17 to break things.

Just upgraded @storybook/react-native to 3.3.0-alpha.4 and it works there, although it does regress Android to the 'attempting to change value of a readonly property' bug we saw on 3.2.16.

So, assuming that the Android fix that was in 3.2.17 makes it to the final version of 3.3.0, upgrading upon release should hopefully fix our issue.

Well caught!
Have you raised a Jira ticket to check future versions and re-upgrade? That way we won't forget to do it 😸
