docs.jenkins.io nginx configuration leaks the nginx version

[PierreBtz]

Service(s)

docs.jenkins.io

Summary

The current configuration of nginx for docs.jenkins.io should be modified to avoid leaking the nginx version.
Not opening as a security issue since it appears the version is up to date but that could become a problem is the project diverges.

Reproduction steps

1. Access a non existing page: https://docs.jenkins.io/toto/
2. Observe the nginx version being returned

Thanks for the report. Since all of our infrastructure code is public, it is easy to get the exact Nginx version: it is not a security concern at all.

But worth fixing
