Parameter names using Finnish notation (trailing $) are not supported

[CarstenLeue]

The following function declaration:

/**
 * Doc of my exported function
 *
 * @param aParam - first parameter
 * @param aObs$ - second parameter
 * @returns the return value
 */
export function myFunction(aParam: string, aObs$: Observable<string>): string {
  return '';
}

causes the "aObs$" parameter to not be recognized. On https://microsoft.github.io/tsdoc/# the second parameter is not documented, but will be documented when I leave out the trailing $.

Trailing $ names are common in Finnish notation to document observables.

This is related to microsoft/rushstack#1055

This should be a pretty easy fix in _parseParamBlock().
