Mish Ushakov e87576fb7c Dockerfile output - change ENV var syntax (#1004)
Current env var syntax won't be anymore supported by Docker and is
currently blocking local development.

```
3 warnings found (use docker --debug to expand):
 - LegacyKeyValueFormat: "ENV key=value" should be used instead of legacy "ENV key value" format (line 2)
```

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Use "ENV key=value" in generated Dockerfiles and add tests; minor
devcontainer path string cast.
> 
> - **Template/Dockerfile generation**:
> - **JS SDK (`packages/js-sdk/src/template/index.ts`)**: Handle `ENV`
instructions and output as `ENV key=value ...`.
> - **Python SDK (`packages/python-sdk/e2b/template/main.py`)**: Same
`ENV` formatting; also cast `devcontainer_directory` to `str` in
devcontainer start command.
> - **Tests**:
>   - **JS**: Add `toDockerfile` test covering `ENV` output.
> - **Python (sync/async)**: Add tests for `ENV` output in generated
Dockerfiles.
> - **Changeset**: Patch releases for `@e2b/python-sdk` and `e2b`.

What is E2B?

E2B is an open-source infrastructure that allows you to run AI-generated code in secure isolated sandboxes in the cloud. To start and control sandboxes, use our JavaScript SDK or Python SDK.

Run your first Sandbox

1. Install SDK

npm i @e2b/code-interpreter

2. Get your E2B API key

  1. Sign up to E2B here.
  2. Get your API key here.
  3. Set environment variable with your API key
E2B_API_KEY=e2b_***

3. Execute code with code interpreter inside Sandbox

import { Sandbox } from '@e2b/code-interpreter'

const sbx = await Sandbox.create()
await sbx.runCode('x = 1')

const execution = await sbx.runCode('x+=1; x')
console.log(execution.text)  // outputs 2

4. Check docs

Visit E2B documentation.

5. E2B cookbook
