Update fleet_packages.json to point to the correct versions for each package that's bundled with Kibana. Please file a PR against main and then backport to 8.4.

I'll include a table below to track the updates needed, as well as the target version for each integration based on what I see published to snapshot today. Once a PR to update each integration is filed, feel free to edit to include a link if I don't get to it first.

If a newer version is planned, please ensure it's published to the snapshot EPR environment before making a change to fleet_packages.json and feel free to update the table below.

Integration	Assignees	Needs Updated To	PR Link
APM ✅	@simitt @axw	8.4.0	#138349
Endpoint ✅	@pzl	8.4.1	#138742
Synthetics ✅	@justinkambic or @dominiqueclarke	0.10.1	#137667
Elastic Agent ✅	@kpollich	1.3.5	#139650
Fleet Server ✅	@kpollich	1.2.0	N/A - No update needed

@axw Can you confirm the intended version of APM that should be in the release? I see an 8.5.0 version published to EPR snapshot, but I assume that 8.4.0 is the intended version to be bundled in the 8.4 release.

Thanks everyone!

@kpollich you assume correctly - it should be 8.4.0.

@pzl or someone else from @elastic/security-onboarding-and-lifecycle-mgt - could you verify the intended version of Endpoint to be bundled in 8.4.0? I took the liberty of bumping the version in #138742 as I had to make some other changes in fleet_packages.json, but I'd like explicit approval from your team before landing the PR.

Everything is good here except Elastic Agent. We're waiting on a 1.3.5 version to be published so we can bundle a fix for elastic/integrations#4007.
