Update CODEOWNERS for integration tests ownership (#9049)

## Summary of changes

Tweak codeowners to work around a bug in our testlogger

## Reason for change

Currently there's a bug in the CODEOWNERS parser with the pattern
`something/**/here` which means it recognizes `/something/else/here` but
not `/something/else`. This is a workaround, until we fix the test
logger

## Implementation details

Add the extra entry

## Test coverage

errr

## Other details

See #9045 for the real
fix

#incident-57303
