* fix: give case insensitive secret more meanigful name
* refactor: use `string` in generating `env:` and `steps:` for workflows
Smaller text generation is much better to read with normal strings than
raw string literals.
* feat: sort keys for `env:` so it's always in specific order
* fix: update test workflows
* Upgrade to the official golangci-lint action and fix some issues it found
* Update deps
* Remove a shadow warning
* Initialize the splitPattern only once
* Initial attempt at supporting $GITHUB_ENV
Needs some polishing and tests
* Now it's actually working
* Replace golang.org/x/crypto/ssh/terminal with golang.org/x/term
* Disable the issue-228 test again
* The linter is picky
* Discovered that the workflow/envs.txt had to exist in certain cases
* Fix small linter issue
