fix name (?) issue with 6 services

[kmitchener]

Run bun run scripts/bundle-compare.ts. It will attempt to create a simple program for each service (to be used to compare bundle size to aws-sdk-v3). That will highlight an issue with these services:

aws-sdk-v3 build failures: arc-region-switch, budgets, codestar-connections, cost-and-usage-report-service, elastic-load-balancing-v2, emr-containers

I've investigated the "arc-region-switch" service. Itty generates the wrong name for it, calling it "ArcRegionswitch" (note the lowercase "s" in switch). Do a similar investigation for the others, find root cause. This is likely causing issue elsewhere.
