Fix regex formatting from nuke_config.yml

[marinalimeira]

Build is current broken with the following error:

❯ houston exec phxops -- go run main.go aws \
  --older-than 1h \
  --force \
  --config ./.circleci/nuke_config.yml \
  --exclude-resource-type iam
ERROR: Error reading config - ./.circleci/nuke_config.yml - yaml: unmarshal errors:

LGTM! Verified it works.

Merging in so we start nuking our account again!

Why was this not caught in the original PR? Do we need to add a regression test?

[yorinasub17]

We don't have a unit test that sanity checks our own internal circleci nuke config, and the nuke job only runs on trunk. I think adding a regression test that confirms it's parseable makes sense!

Great, I added an issue for this ⬆️.

Thank you for creating the issue, Ana!
