Problem: Turns out the release instructions are not entirely accurate.
In order for `xrefcheck-action` to work, the release page must have the
linux binary and the windows zip file attached.
Turns out the recommended way to do this is to edit the "auto-release"
page created by the "Create a pre-release" CI step, see the instructions
here:
https://raw.githubusercontent.com/serokell/scratch/release-binary/scripts/release-binary.sh
Solution: edit the release checklist to include these instructions.
Problem: The results of the repository analysis will always contain
invalid references if the root contains a trailing forward slash.
Solution: Strip the root's trailing slash (if present) when having it be
given as an argument of the System.FilePath.Posix.takeDirectory
function.
Problem: we are going to release this tool and from that point
it would be nice to maintain its changelog.
Solution: add a simple CHANGES.md and update PR template.
Problem: some comments in PR template only matter when this template
is added to the repo, after that they are useless.
Solution: remove those comments.
