Newest Ubuntu switched Firefox to a snap, which breaks karma.

Try to use playwright to download and cache firefox/chromium
and use those for karma.

Compared to puppeteer where we did this some time ago this caches
the browsers globally, and only downloads them when we start the tests.

The goal of this new component is to be a generic selector for API resources,
unlike the organization/person select, which hardcode various things for their
used resource.

Instead this provides some events which can be used to customize the creation of the
URL for fetching as well as for formatting the list of results.

Atm this only handles the organization and no search-as-you-type like the person select,
but maybe this can be extended in the future.

This reverts commit 6324718b.

This reverts commit 3716524b.

Just change all imports and dependencies.

No longer needs babel, but requries an alpha version of the typescript plugin
for eslint 8 support

In newer versions there is now a normal method for this which also supports
dynamically added components.

The static version is deprecated and removed in 2.0, so we need to port here.

This has proper support for rollup while providing the same API.

This is what open-wc recommends now and uses in their @open-wc/testing package

Versions: Lit-Element to 2.4.0 and Lit-HTML to 1.3.0

This fixes a typescript problem and allows us to enable type checking
in the typescript-example package (by removing the ts-nocheck comment)
