Background
We only support 3 thumbnail options in practice, but we show a dropdown with many more options. Going forward, we'll update preferences to display three options: Small, Regular, Large for consistency with the existing font size preference.
User story
As a user I want to be able to have thumbnails smaller or larger than the default.
Requirements
- We update Special:Preferences to have three options (see design)
- Existing values that do not map to the options, map to the new option per details of T424909: [FYI] Default thumbnail size preference for article content is now limited to three sizes
- After deploying the change to preferences, we will run a maintenance script that updates the preference table to reflect the new status quo (cc @Ladsgroup )
