DeedleFake 5d5d04fbb7 feat(golang-rewrite): rename module and move main pacakge to cmd/asdf
* Replace direct `fmt.Println()` usage in a test with `t.Log()`
* Rename `cmd` to `cli`
* Move asdf command from module root
* Fix some linter warnings, thus enabling some tests that were being skipped
* Fix `Makefile`
* Rename module to `github.com/asdf-vm/asdf`
* Fix `TestGetAllToolsAndVersionsInContent/returns_empty_list_with_found_true_and_no_error_when_empty_content`
* Rewrite `Unique()` to be a bit more straightforwards
* Get workflow checks passing again

toolversions.Unique is ever so slightly faster, technically.
