[Doc] Broken links on "concepts-messaging" page

[david-streamlio]

What issue do you find in Pulsar docs?

There are two broken links on the following page

The links to negative acknowledgement and acknowledgement timeout are broken and return 404s

What is your suggestion?

Fix the broken links to point to the correct pages

Do you have any references?

Would you like to fix this issue?

Maybe

Note

• I have researched my question.
