Document deprecated BrAPI fields

• For BrAPI field which are deprecated (ie. backend/src/main/java/fr/inra/urgi/gpds/domain/brapi/v1/data/BrapiLocation.java#getName() we should add a Javadoc explaining what to do with those fields, ie.:

    /**
     * Deprecated in favor of {@link #getLocationName()}
     */
    @Deprecated
    @JsonView(JSONView.BrapiFields.class)
    String getName();

• Update code where those deprecated are currently used, ie backend/src/main/java/fr/inra/urgi/gpds/domain/data/LocationVO.java:150
• Update accordingly BrAPI code (ie. VO?) in frontend classes if they still use deprecated code.
