feat: Added support to use order by in SOQL queries for the core:ExportFiles Add On

[jawills]

Added the ability to use the ORDER BY keyword for SOQL queries when using the ExportFiles addon. This is useful to specify the order of files, so the most recent files in the source org are also the most recent files in the target org.

Example use case with Conga: https://github.com/forcedotcom/SFDX-Data-Move-Utility/issues/779

Usage is as follows:

"afterAddons": [
  {
    "module": "core:ExportFiles",
    "args": {
      "operation": "Insert",
      "contentDocumentLinkOrderBy": "ContentDocument.CreatedDate DESC"
    }
  }
]
