[Salsa] Handel both cases for primitive types in JSDOC

[mhegazy]

JSDoc users commonly use both cases for native types. e.g.:

/**
 * @param {Number} a
 * @param {string} b
 */

Currently Number refers to interface Number instead of the primitive type number.

See relevant discussion in jsdoc/jsdoc#1046
