fix: release Github Action (#228)

The Action to create releases upon a tag being pushed to master has
stopped working as github.event.base_ref is always null
This commit removes the check that the tag has been pushed to the
master branch, must ensure in future that tags to trigger releases
are pushed to the correct location
