• Please update the PR title (which will end up being the commit message) so that it reflects what the update is. doc update is too generic and can be applied to any change in this project. Also, no need to place the Jira ticket id.
• Please sign your commits

There are still many unsigned commits will prevent merging this. Please either sign the old commits or squash them into a new signed one.

On the commits tab, you will see Verified next to signed commits. As as you can see, there are 11 commits in this PR, and 4 of them are not signed. All the commits need to be signed in order to be able to merge PR's.

To squash your commits into one, you can run the following from your branch:

git reset --soft HEAD~<num of commits>
git commit -S -m <your commit message"
git push --force

Here would be 11, and your commit message can be the same as your PR description chore: modify product description.

I added a note on how to squash and sign commits, this is a pre-requisite to merging this.
