Align Filestream Configuration to all Hints templates

[ycombinator]

Cloned from #5686 as that issue now contains a broader discussion about hints templates.

We need to update the prospector block confguration in hint templates

The proposed Filestream configuration should be elastic/integrations#11212

But for eg in logs template

prospector:
  scanner:
    fingerprint.enabled: true
    symlinks: true
file_identity.fingerprint: ~

This is the referencing pipeline responsible to build the packages: https://github.com/elastic/package-storage-infra/blob/main/.buildkite/pipeline.refresh-kubernetes-templates.yml
(Way to trigger it manually here

Where the prospector is defined: https://github.com/ChrsMark/package-storage-infra/blob/54af49b06af4f7e6423574bd0c04206e6ab5e45d/jobs/refreshk8stemplates/job.go#L488-L512

https://github.com/elastic/package-storage-infra/pull/888 is not enough, I need to actually run the job now and merge the PR in the agent repo.
