Proposed commit message

Clarify support of Podman with the Docker module

This change should be backported to 8.16 and 8.17 branches.

We need to add a similar message to the integrations docs https://www.elastic.co/guide/en/integrations/current/docker.html#docker-compatibility

If this is a bug or security fix, could you label this PR @lucabelluccini? 🙏.
For such, you'll need to label your PR with:

• The upcoming major version of the Elastic Stack
• The upcoming minor version of the Elastic Stack (if you're not pushing a breaking change)

To fixup this pull request, you need to add the backport labels for the needed
branches, such as:

• backport-8./d is the label to automatically backport to the 8./d branch. /d is the digit

[mergify]

backport-8.x has been added to help with the transition to the new branch 8.x.
If you don't need it please use backport-skip label and remove the backport-8.x label.

@lucabelluccini running mage update on metricbeat will generate the missing files and get CI green

cd metricbeat
mage update

If we want this to be in 8.x releases, we might want to re-use this PR for the 8.x branch and open a new one for main.

Can this PR be taken over by ingest-docs?

Sure! I've opened up:

• Clarify support of Podman (8.x docs) #43863
• Clarify support of Podman (9.0+ docs) #43864

[kilfoyle]

@lucabelluccini I think this PR can be closed since the backports have all been merged now.

[lucabelluccini]

Thank you @kilfoyle for taking care of this.
