Disable zaps for now

[maelvls]

Context on Kubernetes Slack. I propose to disable both Zapier zaps for now. After this PR gets merged:

• [x] I'll go to the Zapier account using the email login cert-manager-maintainers+zapier@googlegroups.com and the password stored in 1Password (that we have at Jetstack). Then I'll turn the zaps off.

Zapier had fixed the issue 2 months ago (https://community.zapier.com/troubleshooting-99/youtube-the-request-cannot-be-completed-because-you-have-exceeded-your-quota-error-13627/index15.html) but it seems the quota API issue with YouTube is back.
