fix: fix mkdir if the dir already exists

[GreatWizard]

Add parents option on the mkdir command to avoid issue if someone use the action twice in the same github action.

Extract from the mkdir man:

  -p, --parents
         no error if existing, make parent directories as needed

For the record, I got the issue here: https://github.com/GreatWizard/lan-play-status/actions/runs/4393468175/jobs/7693881509

I ran into the same issue. I do a push to Transifex, then a pull from Transifex. The pull has this problem.
