Several Major issues in `vendorListing` area of update-business

[adimmitt]

Several issues here:

On API: https://developers.birdeye.com/#/reference/business/update/update-business

1. There is no documentation related to the entire section of vendorListing

2. Also there is a spelling area in the current implementation code.

Sample part of payload is:

"vendorListing": {
    "venderCategory": "",
    "venderSubcategory1": "",
    "venderSubcategory2": "",
    "venderSubcategory3": ""
  },

which is not right. The spelling of the Subcategories is being spelled vender vs the correct spelling like the header vendor.

3. There is no currently documented API to get the list of Categories here. Was able to determine that this route works but does require a token which is different for the API: https://app.birdeye.com/resources/v1/business/masterdata/vendor
