feat: Camoufox-based crawler template

[barjin]

Adds a Camoufox-based crawler template (camoufox-ts).

Compared to the basic playwright-ts template, camoufox-ts uses the camoufox-js package, which finds the correct latest Camoufox binary in GitHub Releases assets, downloads it and passes the correct launch options to it.

The main.ts script is modified to run the downloaded binary with the correct launchOptions.
Related to #2836

Todo:

• automatize running npm run download-camoufox (maybe put it as postinstall?)
• pass custom fingerprint-modifying options to Camoufox
• maybe store binaries in a system- (or user-)wide location (~/.crawlee/binaries?)

Example code:

import { launchOptions } from 'camoufox-js';
import { PlaywrightCrawler } from 'crawlee';
import { firefox } from 'playwright';

const startUrls = ['https://crawlee.dev'];

const crawler = new PlaywrightCrawler({
    requestHandler: async ({ page, enqueueLinks }) => {
        await page.click('h2');
        await page.click('h3');

        await enqueueLinks();
    },
    maxConcurrency: 1,
    launchContext: {
        launcher: firefox,
        launchOptions: await launchOptions({
            headless: false,
            block_images: true,
            fonts: ['Times New Roman'],
            custom_fonts_only: true,
            humanize: true,
        }),
    },
});

await crawler.run(startUrls);

Execution:

As set, the browser loads no images, uses only one system-installed font (aside from the ones loaded from the page directly) and uses the humanizing script to move the cursor.
