feat: Add support for overriding environment label (#824)
This change looks to add support for the environment label override from fields that #824 requested. This allows users to alter the label themselves which allows a workaround of the issue described in #824.
As this is my first time contributing, I've not fully tidied this PR up yet as I want to get feedback from the maintainers on whether approach is sound/in-line with the vision of the codebase and if there's anything else I should bear in mind.
Is there anything I can do to aid with the progression of this being reviewed?
Bump. I'm waiting on this to use Tanka in any capacity since this is a giant footgun that will destroy deployments and eat data.
Maintainers, any thoughts?
