Only expose `id` and `name` attributes when serializing deploy token

What does this MR do and why?

Related to #353686

In app/views/shared/deploy_tokens/_table.html.haml#L28 we are serializing the entire deploy token object and passing it to the frontend. This means the token and token_encrypted attributes are exposed in the HTML when they don't need to be. The frontend only needs the name and id attributes.

This is a user generated token so the user has already seen the token value but we do tell the user that "The password can not be recovered" so we should not expose it.

It was confirmed with security that this MR can be opened in gitlab-org/gitlab - https://gitlab.com/gitlab-org/security/gitlab/-/issues/615#note_854478625
