chore(tools): eslint update requires promises.all

[TheRealAmazonKendra]

The update on eslint is causing the following error:

@aws-cdk/spec2cdk:   165:3  error  An array of Promises may be unintentional. Consider handling the promises' fulfillment or rejection with Promise.all or similar, or explicitly marking the expression as ignored with the `void` operator  @typescript-eslint/no-floating-promises

This PR has been separated out from 28434 because there are other failures. I am splitting these out to make clear which code is fixing which issue.
