Add jobLocationType property to JobPosting

Submitted MR !30 with the new property jobLocationType.

Attaching a patch for the changes from 062bb7a1 commit.

pfructuoso → made their first commit to this issue’s fork.

The field wasn´t correct. It displayed a `@type` field when it should be only a `text` field. See JobPosting scheme documentation for reference.

After my commit it looks as expected.

This field works but when using it Google also requires the applicantLocationRequirements field to provide at least one Country.

Figured out how to add it;

Now shows as;

            "jobLocationType": "TELECOMMUTE",
            "applicantLocationRequirements": {
                "@type": "Country",
                "name": "AU"
            },

which is showing as valid according to Googles Rich Text tester.

It looks ok according to the documentation.
Output:

  "applicantLocationRequirements": [
    {
      "@type": "Country",
      "name": "Spain"
     },
     {
      "@type": "Country",
      "name": "USA"
      }
   ]
