The added fc-4.6.0.js file is adapted from the public NPM package. The LICENSE remains unchanged from 3.1.0.

Updates are only made to tests and library files in `jstests/write_path/timeseries/pbt/*/` which are under active development as part of SPM-4400.

```js
/*
This file is adapted from https://www.npmjs.com/package/fast-check

To produce the current output file:
1. fast-check@4.6.0 was downloaded from NPM registry

npm install fast-check@4.6..0

2. A bundle.mjs file was created to import and re-export the fast-check library

// bundle-fc.mjs
import * as fc from 'fast-check';
export

;

3. The modules was bundled with esbuild

npx esbuild bundle-fc.mjs \
--bundle \
--format=esm \
--platform=browser \
--target=es2018 \
--minify \
--outfile=fc-4.6.0.js # this file

4. Shims are added for resmoke compatibility
