Jonas Jenwald b89595fd20 [api-minor] Remove the, in legacy builds, bundled ReadableStream polyfill
According to the MDN compatibility data, see https://developer.mozilla.org/en-US/docs/Web/API/ReadableStream#browser_compatibility, all browsers that we support have native `ReadableStream` implementations (since quite some time too).

Hence only Node.js is now lagging behind w.r.t. `ReadableStream` support, and its experimental implementation doesn't really help us given the life-span of the LTS releases (see https://en.wikipedia.org/wiki/Node.js#Releases).
It seems quite unfortunate to bundle a `ReadableStream` polyfill in the `legacy` builds when it's unnecessary in browsers, given its overall size, but fortunately we can avoid that by simply listing `web-streams-polyfill` as a dependency for the `pdfjs-dist` library.

# PDF.js
PDF.js is a Portable Document Format (PDF) library that is built with HTML5.
Our goal is to create a general-purpose, web standards-based platform for
parsing and rendering PDFs.
This is a pre-built version of the PDF.js source code. It is automatically
generated by the build scripts.
For usage with older browsers or environments, without support for modern
features such as `async`/`await`, optional chaining, nullish coalescing,
and private `class` fields/methods; please see the `legacy/` folder.
See https://github.com/mozilla/pdf.js for learning and contributing.
