[A11y][Crawler] Define radiogroups correctly in extraction rules flyo…

…ut (elastic#201191)

## Summary

The issue: keyboard nav with tab doesn't jump between radiogroups
correctly, instead skips some.

Fix the issue with radiogroups selection with `TAB`, following the EUI
docs:
https://eui.elastic.co/#/forms/selection-controls#radio-group

We need to
> Pass a single `name` property to define the group.

Tested locally that this is the culprit of issues when rendering
multiple radio groups in the same flyout.
