fix: generated src/methods4docs.js has an extra line in the JSDocs for methods with no parameters

[shazron]

see listComputedAttributes, createComputedAttribute

This generates a blank line in the JSDoc, and consequently in the types.d.ts file:

1. aio-lib-customer-profile/types.d.ts

   Line 73 in 5318953

2. aio-lib-customer-profile/types.d.ts

   Line 81 in 5318953
