Fix advanced settings category sorting (#83394)

In the advanced settings categories, "Observability" and "Machine Learning" were using uppercase letters in their keys while everything else was using lowercase

This caused them both to show up before the rest of the options in the dropdown and in the sorting in the advanced settings UI.

Add keys for them to the get_category_name module in the advanced settings plugin and use those keys in the plugins that apply these categories.

This also makes it so i18n keys are available for these items.

Fixes #81974.
