Modal

- `modal container exec`'s `--no-tty` flag has been renamed to `--no-pty`.

- The singular form of the `secret` parameter in `Stub.function`, `Stub.cls`, and `Image.run_function` has been deprecated. Please update your code to use the plural form instead:`secrets=[Secret(...)]`.

- In `modal profile list`, the user's GitHub username is now shown as the name for the "Personal" workspace.

- The `modal token new` and `modal token set` commands now create profiles that are more closely associated with workspaces, and they have more explicit profile activation behavior:
- By default, these commands will create/update a profile named after the workspace that the token points to, rather than a profile named "default"
- Both commands now have an `--activate` flag that will activate the profile associated with the new token
- If no other profiles exist at the time of creation, the new profile will have its `active` metadata set to True
- With these changes, we are moving away from the concept of a "default" profile. Implicit usage of the "default" profile will be deprecated in a future update.

- Adds tty support to `modal container exec` for fully-interactive commands. Example: `modal container exec [container-id] /bin/bash`

- The `modal profile list` command now shows the workspace associated with each profile.
