Refactor WorkspaceMemberDto transpilation (#12110)

# Introduction

In a nutshell this PR introduces a `workspaceMemberEntity` to
`workspaceMemberDto` transpilation which was not done but commented as
`// TODO` across the `user resolver`.
Also passed on the `Roles` and `UserWorkspacePermissions` transpilation
We now also compute the roles for the `workspaceMember` resolver ( not
only the `workspaceMembers` )
Some refactor

In the following days about to create a PR that introduces integration
testing on the user resolver

## Conclusion
As always any suggestions are more than welcomed ! Please let me know !
