Added
- Added `versions` command - for example, `dotenv-vault versions [environment]` [discussion](https://github.com/dotenv-org/dotenv-vault/discussions/91)
- Added `version` option to `pull` command - for example, `dotenv-vault pull productionv24`
- Added `.previous` file generation when pulling. This way if you accidently override your local .env file you can still access it. [89](https://github.com/dotenv-org/dotenv-vault/pull/89)
