### Regression Issue

- [ ] Select this option if this issue appears to be a regression.

### Expected Behavior

The list of runtimes should be the list of currently-supported runtimes.

### Current Behavior

The list of runtimes appears to be hard-coded here: https://github.com/aws/aws-cli/blob/fed31fc877fac05142ca632d31db135cb9ddf570/awscli/customizations/wizard/wizards/lambda/new-function.yml#L12-L37

### Reproduction Steps

Run `aws lambda wizard new-function` and open the list of runtimes.

Update `awscli/customizations/wizard/wizards/lambda/new-function.yml` dynamically such that it's consistent with the current list of runtimes.
