Correct Typos in MetaEd Descriptions

(Copied from MODL-184 description):

There are some apparent typo's in metaed descriptions - that surface in swagger docs. The ones I noticed are a result of spaces being removed - likely when manual line breaks were removed.

For example - assessment domain entity - see attachments showing differences between master and current DS 3 branch - and swagger output.

I found one others eyeballing via simple spell check on the swagger output - domain aggregates only (graduationPlans), though a full pass should be taken through entire model
