fix(revision): Increase content field size in revision entity 

Modified the "content" field in the "revision_entity.go" file from 'TEXT' to 'MEDIUMTEXT'. Added a new migration file "v14.go" to handle the transition of the database 'content' field to 'MEDIUMTEXT'. Also adapted the 'command.go' and 'migrations.go' files to handle the new migration. These changes were necessary to accommodate larger revision content sizes.
