Icons in browser notification

Description

As a developer, when a CI Job finishes, a confusing desktop notification is displayed. (Browser notification)

Proposal

It would be great to have a Green check, red cross, yellow warning (and others!) icons to reflect what the status of a build was more easily

Documentation blurb

Overview

When a notification comes up, a lot of information is being displayed in a tiny area. I think some colored icons could be used to facilitate the lecture of the message. First quick look to know pipeline result (good, bad, warnings?), and then look deeply to figure out the details (pipeline id, project, commit, or whatever other details might be helpful)

Use cases

As a developer, I want to keep my focus on my code and new commits I need to push. I don't want to get distracted with a lot of text to know if my changes are building ok so far. A green icon will be enough for success ✅. Red for failures ❌.

Feature checklist

Make sure these are completed before closing the issue, with a link to the relevant commit.
