chore(README.md): remove obsolete square brackets

[JKRhb]

Looking at the README file, I noticed that there currently are obsolete square brackets around the code coverage badge. This PR removes them. However, it might make sense to also wrap the badge with a proper link (there is anything to link to here).

Thanks for the fix 😄.

If we had some kind of page that shows the current coverage report of this CI run even outside of PRs, we could link there instead.
This would also have the advantage that we could see the current coverage state on the current state of main.

Maybe we could create a job summary for the coverage report (see https://github.blog/news-insights/product-news/supercharging-github-actions-with-job-summaries/)?

That sounds good to me :) Should we open an issue for that and add that an a follow-up PR?

@JKRhb Done, see #28
