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.
