Viewport height and width setup, tests failing remotly

[irubido]

---

Locally initSnapEnv installs snap properly, remotly on github actions it fails.
It's impossible to scroll to see button in viewport even locally, but button can still be found ("Approve & install") and test work locally.

dappeteer.page.setViewport({height: 1500, width: 600}) in beforeAll()
sets viewport to late

To Reproduce
Steps to reproduce the behavior:
ChainSafe/test-snaps#2

node_modules/@chainsafe/dappeteer/dist/snap/install.js

    if (opts.hasPermissions) {
        await page.waitForSelector('button');
//ADD THIS TIMEOUT, LINE BELOW
        await new Promise((res) => setTimeout(res, 20000));
        await (0, helpers_1.clickOnButton)(page, "Approve & install");

stretch screen manually to se "Approve & install" button, scroll doesn't work

Expected behavior
initSnapEnv could have viewport in opts: DappeteerLaunchOptions to force height, maybe then tests wouldn't fail remotly

@irubido we probably could close this issue as we increased the viewport size during the installation step. cb6abfc
