chore(store): clear jsdoc/no-defaults warnings in softwarecatalogPlugin

ESLint flagged four `@param {Type} [name=null]` JSDoc shapes as
violations of `jsdoc/no-defaults`. The annotation is meant to declare
optionality (`[name]`) — defaults belong in the description text.
Rewriting the four offenders without semantic change.
