This patch introduces 109 "#smoke" tests - a subset of tests that makes
sure that basic Playwright functionality works. This set is loosely
defined; feel free to add/remove tests to the set. The only goal is to
keep this set minimal & fast to run.
I tried to pick tests so that various parts of Playwright functionality
are exercised.
In this case, there's no protocol version that we can extract for
nsIHttpChannel.
The code that does the redirect is here: 7f3d9fce41/docshell/base/nsDocShell.cpp (L6079-L6095)
To trigger this codepath, we'd need to run test inside a special
docker container that has https server running on the 443 port. We lack
infrastructure for this kind of tests (but it'll be cool to have it).

This now matches what's expected and shown in the terminal (which has always been correct):

NB: This MR is a workaround, but not a root cause fix. It works, but I never fully got to the root cause so a bug upstream may be required. It's unclear whether it's (1) in [`colors`](https://www.npmjs.com/package/colors), (2) in [`ansi-to-html`](https://www.npmjs.com/package/ansi-to-html), or (3) Playwright's use of the two. Since the terminal output is correct, I suspect it is in `ansi-to-html`. For example:
```js
const colors = require("colors");
const Convert = require('ansi-to-html');
const convert = new Convert();
// original (strike incorrectly wraps everything in the HTML)
console.log(convert.toHtml(colors.strikethrough("crossed out") + ' ' + colors.red("red")))
// prints: <strike>crossed out <span style="color:#A00">red<span style="color:#FFF"></span></span></strike>
// workaround
console.log(convert.toHtml(colors.reset(colors.strikethrough("crossed out")) + ' ' + colors.red("red")))
// prints: <strike>crossed out</strike> <span style="color:#A00">red<span style="color:#FFF"></span></span>
```
Fixes#11116
Since our Docker images for Ubuntu 18.04 and Ubuntu 20.04 are almost
identical, we can avoid testing all permutations.
With this patch, we will run our test only under 2 docker
configurations:
- Ubuntu 20.04 arm64 + root user
- Ubuntu 18.04 x86_64 + pwuser
