Upgrade EUI to v14.8.0

[chandlerprall]

Summary

Upgrades EUI from 14.7.0 to 14.8.0, this is a release of EuiDataGrid and some related bug fixes and enhancements to other components.

The unit test changes are a result of an accessibility change which removed a selector used by a couple tests. I've updated the selector to an equally bad choice (eh, maybe a little better), but EUI's table pagination doesn't give much to work with right now.

One change introduced the typo'd aira-modal attribute, there is a subsequent fix for this which we'll make sure follows this PR into the 7.x branch.
