Cache available versions

Please explain the Issue / Feature Request here:

Store available candidate versions, just like the list of candidates.

Rationale: While versions can be retrieved via sdk ls $candidate, or

curl -s https://api.sdkman.io/2/candidates/java/linux64/versions/all

if you want to deal with the list programmatically, it's a bit much overhead for interactive applications.
sdk update could easily store lists of available versions, e.g. as CSV in

.sdkman/var/versions/$candidate

(which could even deprecate .sdkman/var/candidates).
Side note: storing candidates and versions one per line might be more helpful for consuming shell scripts.

Concrete use cases:

• Auto-completion: sdk install java 8.<tab> should complete in meaningful ways.
• Faster sdk ls $candidate (which might warn if the stored data is old).
