Removes the deprecated `accessToken` / `access_token` option from both
SDKs, along with its `E2B_ACCESS_TOKEN` environment fallback and the
`Authorization: Bearer` header it produced. The option was already
deprecated in both SDKs — `connectionConfig.ts` and
`connection_config.py` both pointed at `apiHeaders` / `api_headers` as
the replacement — and E2B access tokens are no longer accepted for API
authentication, so resolving one and putting it on the wire was dead
weight. Requests now authenticate with the API key alone.
Callers who need a bearer token for a custom deployment pass it
explicitly, which is what the deprecation notice already told them to
do:
```ts
// Before
const sandbox = await Sandbox.create({ accessToken: token })
// After
const sandbox = await Sandbox.create({
apiHeaders: { Authorization: `Bearer ${token}` },
})
```
```python
# Before
config = ConnectionConfig(access_token=token)
# After
config = ConnectionConfig(api_headers={"Authorization": f"Bearer {token}"})
```
`Sandbox.envd_access_token` / `traffic_access_token` are unrelated
per-sandbox tokens and are unaffected, as is the volume client's `token`
(which never read the env var — there's a test asserting exactly that).

The CLI half is stacked on top in #1679.
