feat: set svelte context in render fn

[apricote]

Fixes #118
Fixes #136

Description

Support passing the svelte component context in componentOptions.

Previously one had to write a wrapper component that could set the context.

Usage

<!-- Test.svelte -->
<script lang="ts">
  import { getContext } from "svelte";

  const foo = getContext("foo");

  console.log({ foo });
</script>

{foo}

// Test.test.ts
import { render } from "@testing-library/svelte";
import Test from "./Test.svelte";

it("gets context", () => {
  render(Test, { context: new Map([["foo", "bar"]]) });
});

What is the problem with this PR?

[apricote]

As far as I know, there is no problem. This library just does not seem to be actively maintained. I previously asked for a review in the Discord channel, but got no answer there either.

[sebastianrothe]

Okay, can someone from the maintainers add (@apricote or @yanick), so we can proceed? @benmccann

Referencing #182 as well, because it has some tests in it.

For what it's worth, if we want to go with this PR, I'm totally game to rebase my tests on it.

Nah, your PR is the same, but with tests included. Your PR should be favored. This one should be closed. Also this one here is out of date.

[apricote]

Closing in favor of #182 that also includes test for the functionality.

Thank you :)
