Increase the timeout value for linter calculate-docker-image (#96993)
I should have known that this step rebuilds the linter Docker image if it doesn't exists. When it does so, it takes close to 15 minutes to finish, i.e. https://github.com/pytorch/pytorch/actions/runs/4443046530/attempts/1, instead of the regular 2-minute run, i.e. https://github.com/pytorch/pytorch/actions/runs/4442455480/jobs/7798700609.
This x2 the timeout value of this step to 30 minutes to avoid getting timeout flakily.
