Added a section to the page on breaking style and theme changes in v5 about migrating the alternative, array-based syntax for space- and comma-separated values to string-based values necessary for use with Emotion.
Since everything under the heading "Migrate theme styleOverrides to Emotion" was about refactoring local rule references, I opted to take the content in that section and put it under a new sub-header (so the existing h3s became h4s), then I added a second sub-header for the new section about migrating the alternative, array-based syntax.
This is to resolve #41971
