fix(feedback): Fix padding in crash report dialog

[ryan953]

This padding will only kick-in on devices that have a "safe-zone" because of a notch or something like that.

The problem

Devices with a notch or something cutting into the screen have also defined a "safe-zone" where content can render below the notch. By default this makes it so that all the app content is un-obstructed to the user.

It's possible however to override this safe-zone, and render you own stuff around that notch. You can do this on a web-app by setting the following meta tags:

<meta name="apple-mobile-web-app-capable" content="yes" />
<meta name="apple-mobile-web-app-status-bar-style" content="black-translucent" />

With these meta tags in place, if an end-user chooses to add your web-app to their device homescreen then it'll wrap that notch and be hard to read.
The fix is to add extra padding, based on the defined safe-zone. https://developer.mozilla.org/en-US/docs/Web/CSS/env

Some images to help illustrate things are below..

• Web is fine no matter what
• The app, with and without padding added
• The fixed crash report dialog, with it's own padding (this PR)

The Fix

The fix of course is to add some padding that overrides the default. As with all CSS, we're adding overrides for the browser that understand them. Browsers that don't understand constant() or env() or don't have safe-area-inset-top defined will ignore these overrides and use the original padding: 40px or 10px or whatever.

You can test directly on a device by visiting https://pokemon-market.sentry.dev/feedback and adding the site to your homescreen. See getsentry/pokemon-market@a16d14a to see how i made the site app-capable.
