Ghost redirects can be created in JSON or YAML, I did mine with regex and the latter.
You only need one 301 redirect in your
301: ^\/[0-9]+\/[0-9]+\/[0-9]+\/(.+): https://your-domainhere.com/$1
This will match the
/year/month/day/ (or variation there-of) standard and put the ending part directly to the domain.
mayhave to restart your Ghost instance to get the redirects to work and try it in a new/different browser (or in incognito/private mode).
