fix: mark cohort_definition_id as primary key in cohort_definition table for v5.3 and v5.4 #787

Problem

The cohort_definition_id field in the cohort_definition table is not marked as a primary key in the CSV spec files for v5.3 and v5.4, even though it is the natural primary key for that table (each cohort definition has a unique ID). The v6.0 CSV correctly marks it as a primary key.

Affected Files

• inst/csv/OMOP_CDMv5.3_Field_Level.csv — cohort_definition,cohort_definition_id has isPrimaryKey=No
• inst/csv/OMOP_CDMv5.4_Field_Level.csv — same issue
• docs/cdm53.html — generated HTML shows Primary Key=No
• docs/cdm54.html — generated HTML shows Primary Key=No

Proposed Fix

Change isPrimaryKey from No to Yes for the cohort_definition_id field in the cohort_definition table in both v5.3 and v5.4 CSV files, and update the generated HTML docs accordingly.
