Convert recreateClosed to enum like

[rarkins]

What would you like Renovate to be able to do?

Support values of never, auto and always for recreateClosed. auto maps to the current default false value, and always maps to current true value. The use of never would be for people to say they don't want immortal PRs reopened.

If you have any ideas on how this should be implemented, please tell us here.

Per above

Need to make sure PR description is correct in case of immortal PRs and recreateClosed=never

Is this a feature you are interested in implementing yourself?

No

Since we have decided to not use enums anymore. I think we will need to convert it to a string type.

type RecreateClosed = 'auto' | 'always' | 'never';
