Add OUIA props to VictoryContainer

[dlabrecq]

In order to better support automated testing, we would like to add the properties below to the root HTML element output by VictoryContainer.

These properties are defined by the Open UI Automation (OUIA) 1.0-RC spec.
https://ouia.readthedocs.io/en/latest/README.html#ouia-component

data-ouia-component-type
data-ouia-component-id
data-ouia-safe

Fixes #1624

@dlabrecq Thank you for this PR and for updating the docs to go along with. Everything looks great. Would this work also be an appropriate addition to victory-native? Let me know if so, and I can PR the corresponding changes there pretty quick. If not, would you please do add a note to the new props you've documented to make it clear that they are web only? Thanks!

Yes, these props would apply to React native as well.

Great! I'll release a patch version and a docs update right now, and native changes this afternoon
