Remove 800.103 and modify documentation reference

Some alarms reference to "System Administration Manual" but this
document does not exist. It was changed to a generic documentation
reference.

The 800.103 alarm has been deprecated so it is deleted from the
events.yaml file.

Test plan
Pass:
* Build fm-doc package. Check that all parsing checks were run and
package was built successfully.
