feat(bootstrap): delete noncurrent versions after 30 days

[kaizencc]

CDK assets in the bootstrap bucket are content-addressed and immutable so we never naturally create noncurrent versions.
However, with the introduction of the cdk gc command, we now have the capacity to delete unused objects in the bucket. Because the bucket is versioned by default, the delete command actually just replaces the object with a new dummy version (thus the deleted object becomes noncurrent).

Now that noncurrent objects can happen, if one utilizes cdk gc, we are updating the bootstrap template to retain them for 30 days rather than 365 days.

Update to bootstrap version 24 to use this new lifecycle policy in conjunction with cdk gc.
