chore: Move to monorepo ❗ ❗ ❗ (#7342)

* chore: Move to monorepo

Reorganized everything. Removed broken tests from docs app so we can run tests in CI for that again. Some tests are better than no tests. Updates the GitHub actions, some of the README stuff, and build scripts

* chore: fix github action commands

* chore: Update tslint-etc locations

* chore: update README with more information about yarn

* chore: fix alias generation location

* chore: update lodash to fix TS latest errors

-## Installation and Usage
-
-### ES6 via npm
-
-```shell
-npm install rxjs
-```
-
-It's recommended to pull in the Observable creation methods you need directly from `'rxjs'` as shown below with `range`.
-If you're using RxJS version 7.2 or above, you can pull in any operator you need from the same spot, `'rxjs'`.
-
-```ts
-import { range, filter, map } from 'rxjs';
-
-range(1, 200)
-  .pipe(
-    filter((x) => x % 2 === 1),
-    map((x) => x + x)
-  )
-  .subscribe((x) => console.log(x));
-```
-
-If you're using RxJS version below 7.2, you can pull in any operator you need from one spot, under `'rxjs/operators'`.
-
-```ts
-import { range } from 'rxjs';
-import { filter, map } from 'rxjs/operators';
-
-range(1, 200)
-  .pipe(
-    filter((x) => x % 2 === 1),
-    map((x) => x + x)
-  )
-  .subscribe((x) => console.log(x));
-```
-
-## Goals
-
-- Smaller overall bundles sizes
-- Provide better performance than preceding versions of RxJS
-- To model/follow the [Observable Spec Proposal](https://github.com/zenparsing/es-observable) to the observable
-- Provide more modular file structure in a variety of formats
-- Provide more debuggable call stacks than preceding versions of RxJS
-
-## Building/Testing
-
-- `npm run compile` build everything
-- `npm test` run tests
-- `npm run dtslint` run dtslint tests
+## Development
 
-## Adding documentation
+Because of [this issue](https://github.com/npm/rfcs/issues/287#issuecomment-1727960500) we're using `yarn`. (Basically the docs app uses `@types/jasmine`, and the package uses `@types/mocha` and they get hoisted to the top level by `npm install` with workspaces, and then TypeScript vomits everywhere when you try to build).
 
-We appreciate all contributions to the documentation of any type. All of the information needed to get the docs app up and running locally as well as how to contribute can be found in the [documentation directory](./docs_app).
+1. `cd` to the repository root
+2. `yarn install` to install all dependencies
+3. `yarn workspace rxjs test` will run the RxJS test suite
+4. `yarn workspace rxjs.dev start` will start the rxjs.dev documentation site local development server
