Remove KUI usage in `visualizations`

[joshuarrrr]

Based on a quick initial search, this plugin only defines some kui classes in the DisabledLabVisualization component:

To resolve

• [ ] This placeholder text and icon should be replaced with OuiEmptyPrompthttps://oui.opensearch.org/1.2/#/display/empty-prompt
• [ ] The wording should be updated to remove "lab" and "lab mode" as those are Kibana terms - we also want to remove the word "please" as it doesn't align with our language styleguide. So the new text would read "[vispanel title] is an experimental visualization. Enable experimental visualizations within Advanced Settings. "
• [ ] A deep link to the Visualizations panel in Advanced Settings should be placed in the message

@joshuarrrr Hello, I want to work on this issue, can you please assign it to me?

@joshuarrrr You have highlighted kuiVerticalRhythm class to be renamed to have component scoped class name, however, in the SCSS file we also have classes starting from kui such as:

• kuiVerticalRhythmSmall
• kuiVerticalRhythmLarge
• kuiVerticalRhythmXLarge I assume that they also should be renamed, right?

[joshuarrrr]

We're not actually interested in renaming the KUI classes themselves, because we want to get rid of KUI altogether. What this issue aims to do is to remove any KUI classes added to elements in the visualize plugin, without changing the actual CSS applied to those elements. So while there are many other KUI classes defined, we only care about the ones that are still in use and providing styles of some sort.

@sayuree are you still working on this issue? It seems to be stale. If not, we'd like to unassign you.
