Fix type errors in formula.test.tsx

[nickofthyme]

Fix typescript type errors from #175178 removing @ts-expect-error comments.

x-pack/plugins/lens/public/datasources/form_based/operations/definitions/formula/formula.test.tsx

This error involves types that are a bit complex, a general approach in described below. See #176114 (review) for more details.

Here is a commit a20a96c with a start to the fix but is missing the correct params type.

---

The mock function of createOperationDefinitionMock is trying to conform to multiple type definitions in a single function.

I reworked the types to pass a generic type based on the input type, with it defaulting to the field type.

This works for almost all cases, haven't checked other files 🤞🏼, except for used with the label: 'moving_average', see next comment 👇🏼 .

When defining the moving average definition like here...

kibana/x-pack/plugins/lens/public/datasources/form_based/operations/definitions/formula/formula.test.tsx

Lines 58 to 74 in a20a96c

	moving_average: createOperationDefinitionMock('moving_average', {
	input: 'fullReference',
	operationParams: [{ name: 'window', type: 'number', required: true }],
	filterable: true,
	getErrorMessage: jest.fn(() => ['mock error']),
	buildColumn: ({ referenceIds }, columnsParams) => ({
	label: 'moving_average',
	dataType: 'number',
	operationType: 'moving_average',
	isBucketed: false,
	scale: 'ratio',
	timeScale: undefined,
	params: { window: 5 },
	references: referenceIds,
	filter: getFilter(undefined, columnsParams),
	}),
	}),

The type of params: { window: 5 } is pointing to this type here thus why adding the window prop fixes the error.

But I think window type should be pulling from MovingAverageIndexPatternColumn instead which is here...

kibana/x-pack/plugins/lens/public/datasources/form_based/operations/definitions/calculations/moving_average.tsx

Lines 45 to 51 in a20a96c

	export type MovingAverageIndexPatternColumn = FormattedIndexPatternColumn &
	ReferenceBasedIndexPatternColumn & {
	operationType: typeof MOVING_AVERAGE_ID;
	params: {
	window: number;
	};
	};
