GoogleSheets adaptor should support multi-range update and throttling

[redietr]

1. Multi-Range Support for batchUpdateValues

Problem

The current batchUpdateValues implementation only supports updating a single range at a time. When users need to update multiple non-contiguous ranges, they must call batchUpdateValues multiple times, which:

• Quickly exhausts Google's rate limit (60 writes/minute/user)
• Defeats the purpose of the batch API
• Causes failures in parallel workflow scenarios

Current Behavior

batchUpdateValues({
  spreadsheetId: '1abc...',
  range: 'Sheet1!A1:B2',
  values: [['a', 'b'], ['c', 'd']],
  valueInputOption: 'RAW'
});

This sends a single ValueRange object to the API.

Proposed Behavior

Support a data parameter that accepts an array of ValueRange objects, aligning with Google's spreadsheets.values.batchUpdate API:

batchUpdateValues({
  spreadsheetId: '1abc...',
  data: [
    { range: 'Sheet1!A1', values: [['value1']] },
    { range: 'Sheet1!B5', values: [['value2']] },
    { range: 'Sheet1!D10:E11', values: [['a', 'b'], ['c', 'd']] }
  ],
  valueInputOption: 'RAW'
});

2. Request Throttling / Rate Limit Handling

Problem

Google Sheets API enforces a limit of 60 write requests per minute per user. When multiple OpenFn workflows run in parallel or a single workflow makes rapid sequential calls, users hit 429 Too Many Requests errors.
