[IOPS-3625] Reverting Obs-Lab back to previous iteration (#706)

* Reverting Obs-Lab back to previous iteration

Updated the binding strength for Observation.code to 'preferred' and removed several elements related to coding slices and references.

* Delete valuesets/ValueSet-UKCore-PathologyAndLaboratoryMedicineProcedures.xml

* Delete valuesets/ValueSet-UKCore-PathologyBoundedCodeListObservables.xml

* Update version and date in UKCore-Observation-Lab.xml

* Update UKCore-Observation-Lab-Albumin-Example.xml
