Thanks for signing the CLA. The EasyCLA bot should pick up on that if things are complete, but there is still something it doesn't like. Can you try clicking the doc link in the note from EasyCLA and following the instructions there? It is particular about the way you submit stuff so that it can verify you've signed the CLA. We are not permitted to accept a PR unless EasyCLA gives the 👍 so we need to get that resolved.

Aside from that, the PR is small and looks reasonable. Can you expand on why it's needed though? I see you adding the field to the struct, but nothing is using it. What's missing by not having it in there? What doesn't work at present? I'm just trying to understand the purpose of adding it. Thanks

Thank you for such a quick response! Looks like I've managed to settle down CLA issues :D

I'm aware that pipeline-builder itself doesn't have any uses for environments as of this day, perhaps it will be useful in the future since GitHub supports it. As for my needs - I'm using pipeline-builder as a Go library in my separate application that converts DroneCI pipelines into GHA workflows. Most of the workflows require the usage of environments, hence it would be great if the builder supported this field 👍

OK, thanks for the additional detail. That seems reasonable. I will need to review and see how this will impact our pipelines. I'll get back to you shortly.
