UploadFileParams uses old paramter: convert_placeholder

[Chris Chow]

Describe the bug
File upload does not respect convert_placeholder parameter.

To Reproduce

1. Use the node-js-api to upload a File.
2. Set convert_placeholder to false.

await this.lokaliseApi.files.upload(this.projectId, {
  data: content,
  filename: fileName,
  lang_iso: languageISOCode,
  convert_placeholder: false,
  tags: ['Pushed'],
  replace_modified: this.replaceModified,
  skip_detect_lang_iso: true,
})

3. File in Lokalise uses the Lokalise universal placeholder

Expected behavior
I expect the original placeholder to preserved.

Your environment:

• Node version: 12.22.3

Additional context
UploadFileParams does not use convert_placeholders which is the correct param in the latest version of the API. https://app.lokalise.com/api2docs/curl/#transition-upload-a-file-post. Rather it uses convert_placeholder, without the s. I contacted someone on Lokalise support and they mentioned convert_placeholder is the V1 version of that param.
