minor: flaw in readme description

[YevheniiSemendiak]

In readme.md's instruction, of how to run git-chglog, you need to add extra params for docker option:
docker run -v "$PWD":/workdir quay.io/git-chglog/git-chglog --version -> docker run -it -v "$PWD":/workdir quay.io/git-chglog/git-chglog --version

Otherwise, it wouldn't work.

Your Environment

• OS: ubuntu
• Docker version 23.0.2, build 569dd73
• git-chglog version: 0.15.4
