docs: fix default period in simulate/iter/periodic-sinc JSDoc

[Planeshifter]

Description

What is the purpose of this pull request?

This pull request:

• corrects the documented default for options.period in the @stdlib/simulate/iter/periodic-sinc JSDoc from 10 to 100, matching the implementation, README, REPL text, and TypeScript declarations.

simulate/iter/periodic-sinc

The lib/main.js JSDoc declared [options.period=10], while the implementation initializes opts.period to 100 and every other documentation surface states 100. In simulate/iter, JSDoc option defaults agree with implementation defaults in 15 of 16 packages (94%), and this package was the sole outlier. Documentation-only change, with no change in behavior.

Any other information relevant to this pull request? This may include screenshots, references, and/or implementation notes.

Found via a cross-package drift check over simulate/iter (16 packages), which compared each package's structure and API conventions against its siblings. Other outliers (awgn, awln, and awun lack lib/validate.js; awgn, awln, awun, and periodic-sinc take positional arguments ahead of options) were reviewed and left as is because they reflect real API differences: the noise packages transform an input iterator and use PRNG options, and the periodic sinc function requires an order n.
