update secops orb (apollographql/federation-next#59)

## Motivation / Implements
This PR updates the version of the SecOps orb used in this repo. Version
2.0.0 of the orb included an issue on the gitleaks job that prevented
the job from running on PRs created from forks. The issue was caused by
a default configuration in CircleCI which prevents providing secrets
provided through CircleCI contexts to PRs created from forks. This
default configuration is probably the correct one, so we needed up
update the SecOps orb to properly operate on PRs from forks.
