refactor(cli): remove ensureAccessToken from template create (#1400)

## Summary

Removes the `ensureAccessToken()` call (and its now-unused import) from
`e2b template create`. The command authenticates solely via the API key
(`ensureAPIKey()`), so the access-token check was redundant.

## Changes

- Drop `ensureAccessToken` import and call in
`packages/cli/src/commands/template/create.ts`.
- Add a patch changeset for `@e2b/cli`.
