fix: add permission to execute commit-msg hook

[wuda-io]

Proposed changes

The husky hook did not work under ubuntu. I found the solution here:
https://stackoverflow.com/questions/8598639/why-is-my-git-pre-commit-hook-not-executable-by-default

Also found out that git saves the permissions of the files too, so I
changed the permission of the commit-msg file to work under linux systems.
chmod ug+x .husky/commit-msg

Also tested.
