fix(aws-serverless): Fix build of lambda layer (#12083)

We previously adjusted our lambda layer auto initialization in
#12017. This
unfortunately changed the build output of the `awslambda-auto`
bootstrapping script which required a package that isn't included in the
layer (`@sentry/node`). This PR fixes the `awslambda-auto` file; local
testing showed no more imports from `@sentry/node`.

fixes #12074
