Updated Consul Prometheus documentation

[algchoo]

Changes

• updated consul image due to name change, updated minimum version
• updated the image name in the documentation for consul

Details
Updated the minimum version for the exporter in the documentation and metadata. Due to the image name changing, that is updated (just noticed that I missed this part, sorry for the confusing commits) in the documentation, as well.

Just double-checking, why is this version bump necessary? Back when we published this, we did verify that consul 1.13.x does work and you can get the necessary metrics scraped by GMP?

Should we only bump minimum supported exporter versions when there is actually a breaking change in the config (like in #580) or if the new version emits some new metrics that we are showcasing in the dashboard?

I agree with you on this, but wasn't sure initially. These changes do not have an effect on the dashboard/alerts, no other breaking change that I'm aware of exists. I'll update this.

If we are keeping the minimum version as is, I don't see a reason to change the documentation either, even with the newer image having a slightly different name, I'll close this PR.
