The **check_api_changes** job is sometimes cancelled when the job
exceeds the timeout of 20 minutes. This can happen when steps are
retried (introduced in
#3010).

Increased the timeout from 20 minutes to 60 minutes. Being generous
here, as a successful run of step `Check API changes with retry` should
take around *14 minutes*. If we try that step three times, a 60 min
timeout should be able to cover the time needed for 3 tries and other
steps in the run.

## Validation

<!--
Describe how changes in this PR have been validated. This may include
added or updated unit, integration and/or E2E tests, test workflow runs,
or manual verification. If manual verification is the only way changes
in this PR have been validated, you will need to write some automated
tests before this PR is ready to merge.

For changes to test infra, or non-functional changes, tests are not
always required. Instead, you should call out _why_ you think tests are
not required here.

If changes affect a GitHub workflow that is not included in the PR
checks, include a link to a passing test run of the modified workflow.
