Fix getSheet method to accept sheetId

[ggoranov-smar]

Fix getSheet URL and parameter (#161)

Problem

getSheet does not take sheetId as the parameter name and routes to the /sheets collection URL instead of /sheets/{sheetId}.

Changes

• lib/sheets/get.js
  • Added a dedicated getSheet function that builds the URL as sheets/{sheetId} using the new buildUrl(sheetId) helper.
  • Refactored getSheetAsCSV, getSheetAsPDF, and getSheetAsExcel to directly call the requestor with sheetId-based URLs instead of delegating to listSheets.
  • Replaced _.extend(optionsToSend, ...) (mutating shared state) with spread syntax to prevent URL bleed-through between calls.
• README.md — Updated example to use sheetId instead of id.
• Tests — Updated endpoints.spec.ts and sheets.spec.ts to reflect the corrected parameter name and expected URLs.
