* chore: add /v2 to import module path
go mod requires semantic versioning with versions greater than 1.x
This was a mechanical update by running:
```
go install github.com/marwan-at-work/mod/cmd/mod@latest
mod upgrade
```
Migrate generated files to import /v2
* Fix gen
* prompt for confirmation before deleting templates (#2830)
* populate templateNames from the interactive picker too
* allow skipping delete confirmation prompt with --yes flag
* eliminate unnecessary newline
* test both confirmation of delete and `--yes` with no confirmation
* fix failing test that needed --yes
* remove unnecessary empty line the linter disliked
* make the tests correct
