Fix(ed) maven-central badge

[rolandtritsch]

Hi @ckipp01,

I noticed that the maven-central badge in the README did not show the correct version number.

Looked into it.

The heroku app seems to have stopped working (shows the wrong/an old(er) version).

Tried shield.io, but it cannot find the version.

As a workaround I suggest to use the github-release version.

Wanted to push that commit to my fork and do a PR, but pushed it by accident to scoverage. Sorry about that.

Doing this issue to document what happened.

Let me know, if you have a better idea. Happy to do a PR to revert the change.

You should also be able to use the badges from scaladex.

Yep. That works. Here is the PR. Feel free to merge or let me know, if you want me to merge it.
