Serverless Stack

<@U01JVDKASAC> After updating  from v0.58.0 straight to v0.59.4 I had similar issues to <@U01RWQ0H3B3> that you said will have a "helping hand included": <https://serverless-stack.slack.com/archives/C01JVDJQU2C/p1642148371000200?thread_ts=1642130318.050400&amp;cid=C01JVDJQU2C>
Follow up in the thread for readability

Mine read:
 :x:  lktest-altera-stack-Altera failed: Error: lktest-altera-stack-Altera: This CDK deployment requires bootstrap stack version '6', found '5'. Please run 'cdk bootstrap'.

Works after manually running `cdk bootstrap` with each of my environments, but no help from SST CLI, that was mentioned in the linked message, did appear

You're probably checking whether *any* bootstrap stack exists on the account, I'd extend it to a version verification

Other than that my transition to CDK v2 went flawlessly thanks to the docs provided. Great work! :pray:

Submitted a PR. Will merge after tests pass.
