packages/prometheus: Upgrade to package format_version v3

[shmsr]

Proposed commit message

Upgrade to package format_version v3. Tested using elastic-package (pipeline, static, etc.) and also linting and building. Also did basic testing by scraping data from Prometheus Server itself and populating the dashboard. Works as expected. For testing, I used 8.16.1 cluster.

Nice to see that we did not have to exclude any checks in validaton.yml

LGTM!
I only did a package build! Apart from that it would be useful to such stories to add the screenshots section or some verification logs that some basic tests had run and nothing broke

@gizas Makes sense. I should've put it. So for testing I have all the elastic-package tests (e.g., pipeline, static, etc.), and also linting to check for validations (SRV...). Everything looks good. I did basic testing by scraping data from Prometheus Server itself and populated the dashboard. I'll put the pics here:

I have also updated the PR description.
