See parent task T202132: EPIC: Generate one-off metric snapshots for mobile editing documentation for more information on background and acceptance criteria.
How many edits are made using the visual and wikitext editors? This is complex to define, because some wikis use visual editor by default on desktop, and others don't, and on mobile wikitext is the default everywhere, so calculating an overall percentage based on such disparate configurations will generate flawed data. This needs to be split out based on which the default editor is for desktop, then mobile done separately.
Expected snapshot output:
|Metric||Visual editor percentage||Wikitext editor percentage|
|Desktop (visual editor default wikis)||%||%|
|Desktop (wkitext editor default wikis)||%||%|
(sum of each item in the rows should add up to 100%)
