Add State to ListProjectAccessTokensOptions

Created by: elchenberg

GitLab 17.2 added the state attribute to the ListProjectAccessTokens API: https://docs.gitlab.com/ee/api/project_access_tokens.html#list-project-access-tokens

I am not very experienced with Go but since it seems to be a small change I might give it a try and open a pull request if it is okay with you:
