Update dependency got to v9 (#10861)

no issue 

- The underlying issue is the change in retry behavior in 'got' (sindresorhus/got@a3e77de)
- Now 500 responses trigger 2 default retries
- Renamed retries -> retry. As mentioned in https://github.com/sindresorhus/got/releases/v9.0.0
- Added response body error check
