**Description of the issue/feature this PR addresses:**
Improve job posting structured data with modifying remote job specific XML tags when the job is a remote job, in order to match the requirements from [Google Search results Job Posting structured data document](https://developers.google.com/search/docs/appearance/structured-data/job-posting)

Currently Odoo website's job detail page with remote job is not passing the rich results test from [Google search rich result test](https://search.google.com/test/rich-results), as jobLocation will be empty content when it is a remote job. In order to be eligible in appear in google's enriched search result, jobLocation should not be used in a remote job, instead jobLocationtype & applicantLocationRequirements should be applied.

**Current behavior before PR:**
Empty jobLocation content when the job is a remote job. No jobLocationType & applicantLocationsRequirement tag for remote job which not matching with google search result's requirement.

**Desired behavior after PR is merged:**
jobLocation tag will be removed if the job is a remote job. jobLocationType will be appeared and the content will be TELECOMMUTE, and applicantLocationRequirements will be company's country.
