Update longhorn.adoc

 Hi ,
I have made a small correction to address a typo in the code. This pull request aims to fix the error and improve the overall code quality.
Please review the commit and consider merging it into the main branch. Feel free to provide any feedback or suggestions for improvement.

Thank you for maintaining this open source project, and I appreciate the opportunity to contribute! I'm learning kubernetes so that I can contribute into larger problems. It would be helpful if you can share some resources with me for learning.

 *Statement on alignment with CNCF mission:*
 
-Longhorn project aligns with CNCF's mission to make cloud-native computing ubiquitous. Today, persistent storage support varies from Kubernetes cluster to Kuberentes cluster. As a result, users cannot deploy stateful workloads that require persistent volumes and expect their stateful workloads to work on any Kubernetes cluster. By creating a portable and lightweight implementation of persistent storage volumes, Longhorn can make persistent storage support available on every Kubernetes cluster and thus can help drive the adoption of Kubernetes technology.
