Create a view positions page

Description:
Departments should be able to view any position from the Positions page This page serves as view of a position and should display all information associated with the current version of the position.

Requirements:
Create an Individual Position Details page.
Display:
-Position Title
-Position Code
-WLS Level
-Last Revision Date

Notes:
This page displays only the current version.
Position history is implemented in Issue https://github.com/BCStudentSoftwareDevTeam/lsf/issues/612.

P.S: This sub-issue was created due to the nature of the main issues where we had to manage positions using actions like view description, edit and showing status of positions. Pull request to this sub-issue only solves the ones listed above. This sub-issue will help progress into the main issue.

Beginne mit der bestehenden Positions page und verfolge, wie die aktuelle Version einer Position geladen wird. Verwende Issue 612 für die Abgrenzung rund um die Positionshistorie. Als erledigt gilt die Aufgabe, wenn eine Individual Position Details page den aktuellen Position Title, Position Code, WLS Level und Last Revision Date anzeigt, ohne eine Positionshistorie hinzuzufügen.
