[Fleet] Allow to link to Integration without specifying the concrete version

[simitt]

At the moment the exact version is specified when navigatin to an Integration in Fleet, for example <host>:<port>/app/fleet#/integrations/detail/apm-0.1.0-dev.5/overview.

When linking to an Integration from some other Kibana app, this requires to know about the Integration versions. It would be easier if a URL without the version would just show the installed, or if not installed the latest available, Integration.
Example: <host>:<port>/app/fleet#/integrations/detail/apm/overview.

Edit: this issue is currently blocked until we figure out plans for Integration UI and capacity for that work in 7.14.

@ph I think this is needed to link from the add data UI to the APM integration in Fleet

cc @ruflin @paul-tavares @neptunian since I know we've debated "always show latest" vs installed in the past

I like the suggestion from @simitt

URL without the version would just show the installed (version), or if not installed the latest available, Integration.

@jfsiii But I remember there was a catch to this?

[jfsiii]

@ruflin I don't recall anything specific, but will look into it. I know we have several places that assume/require the latest version, but hopefully that won't affect us here.

[ruflin]

Relabeled to 7.14, hope this is ok.

[simitt]

@ogupte @cauemarcondes this is the issue regarding the latest package.
@jen-huang I see this was moved to TODO some time ago, is this still planned/feasible for 7.14?

[jen-huang]

@simitt Yes, I believe @kpollich will be looking at this.
