CircleCI deploy fails due to restricted context

[mindctrl]

When the release deploy jobs run in CircleCI (introduced in #179), the job fails because the GitHub Actions bot does not have access to the restricted Contexts stored in CircleCI.

Example: https://app.circleci.com/pipelines/github/wpengine/wp-graphql-content-blocks/88/workflows/fea1e32f-40c9-41c0-ba94-5eba26a57d74

Re-running the job manually as a user with the appropriate team access in GitHub results in the job working as expected. We need to fix this so it's automated.

CircleCI is not actively used in this project now, as a result we are cleaning up and closing this issue
