[TC] [CV] Timeout linting

What's the issue?
We're seeing timeouts linting in CV, I suspect this is because I removed the timeout and replaced it with a top-level one when we added versioning.

The default timeout is a minute, so whilst the top-level timeout remains the same, one module may overrun the 1m timeout.

What's the fix?
Reinstate the 10m timeout at the golangci-lint level.
