Material-ui: [Tooltip] Outdated TooltipClassKey type

[dufia]

https://github.com/mui-org/material-ui/blob/master/packages/material-ui/src/Tooltip/Tooltip.d.ts#L49 should also include the arrow key. A problem if you are using TS.

Hey, I've noticed 4.7.1 was released and it included this fix. But somehow, it didn't make it into the released code. When I check my node_modules for @material-ui/core/Tooltip/Tooltip.d.ts, type TooltipClassKey remains unchanged. Any ideas why?

I definitely have 4.7.1 installed.

@dufia #18645 was not included in 4.7.1. It was released before the PR was merged: https://github.com/mui-org/material-ui/compare/v4.7.1...master
