docs: Add documentation to a subset of available extensions (#24138)
I was able to use my experience with some of the Deno extensions to
flesh out their documentation a bit

I've provided docs for the following:
- web
- fetch
- net
- webidl
- url
- io
- crypto
- console

# deno_crypto
**This crate implements the Web Cryptography API.**
Spec: https://www.w3.org/TR/WebCryptoAPI/
## Usage Example
From javascript, include the extension's source, and assign `CryptoKey`,
`crypto`, `Crypto`, and `SubtleCrypto` to the global scope:
```javascript
import * as crypto from "ext:deno_crypto/00_crypto.js";
Object.defineProperty(globalThis, "CryptoKey", {
value: crypto.CryptoKey,
enumerable: false,
configurable: true,
writable: true,
});
Object.defineProperty(globalThis, "crypto", {
value: crypto.crypto,
enumerable: false,
configurable: true,
writable: false,
});
Object.defineProperty(globalThis, "Crypto", {
value: crypto.Crypto,
enumerable: false,
configurable: true,
writable: true,
});
Object.defineProperty(globalThis, "SubtleCrypto", {
value: crypto.SubtleCrypto,
enumerable: false,
configurable: true,
writable: true,
});
```
Then from rust, provide:
`deno_crypto::deno_crypto::init_ops_and_esm(Option<u64>)` in the `extensions`
field of your `RuntimeOptions`
Where the `Option<u64>` represents an optional seed for initialization.
