ci: revert normalizing host.name in query

[kb-newrelic]

Summary

• Reverting the 'normalization' of the distro in the host name as it causes nightly to fail. I initially thought it would be worth for readability but it also forces normalizing it in terraform which just becomes cumbersome to remember. If readability becomes an issue, adopting a different separator than - might be preferable than trying to shoehorn all segments that naturally contain hyphens into using a different character.
