Description of problem:

In our official documentation [1] there is a small typo inside 'Description' section of CatalogSource/.spec.grpcPodConfig.securityContextConfig. At the end of the description section, an additional acute/back quote symbol (`) got inserted at the end of the URL
"https://kubernetes.io/docs/concepts/security/pod-security-admission/". Upon clicking on this URL, its redirecting to 404 error.
This bug is raised to correct the typo mistake.
