SAM debugconfig: fix env-vars.json (#1167)

- Problem: Since 7b5aae7 , `target=template`
  uses the original resource name instead of the dummy name
  `awsToolkitSamLocalResource`.  But we forgot to update the name in
  `env-vars.json`, so envvars specified in `launch.json` were not
  applied.
- Solution: use the correct name in `env-vars.json`,
