0.15.0 2021-08-13 maintenance release, update not required

Issue #53 describes an issue with ignoring Markdown regions with code fences. This was an issue in pyspelling, which is the core component in this action. Luckily @facelessuser, the maintainer of pyspelling was to fix it. So the requirement for pyspelling was bumped from 2.6.1 to 2.7.3

Thanks to @supernovae and @facelessuser
