ESQL: Generate kibana inline docs

docs/reference/esql/functions/README.md

@@ -5,6 +5,8 @@ The files in these subdirectories are generated by ESQL's test suite:
 * `signature` - railroad diagram of the syntax to invoke each function
 * `types` - a table of each combination of support type for each parameter. These are generated from tests.
 * `layout` - a fully generated description for each function
+* `kibana/definition` - function definitions for kibana's ESQL editor
+* `kibana/docs` - the inline docs for kibana
 
 Most functions can use the generated docs generated in the `layout` directory.
 If we need something more custom for the function we can make a file in this
