[Website]: Document that our Elastic Agent docker images always run as unprivileged #3235
Description
Type of issue
Missing information
What documentation page is affected
https://www.elastic.co/docs/reference/fleet/elastic-agent-unprivileged
What happened?
Elastic Agent docker images always run as unprivileged.
This is normal as running a container as root is typically an anti-pattern.
It is quite common to see a warning in the Fleet UI when running the system integration inside a docker container.
We should tell the users what to do.
Additional info
I think the content should be contributed by the Elastic Agent team.
