ServiceAccounts and GroupServiceAccounts do not permit custom username or name attributes

[Scrumplex]

Description

• Node.js version: 20.11.1
• Gitbeaker version: 39.34.3
• Gitbeaker release (cli, rest, core, requester-utils): core
• OS & version: NixOS nixos-unstable

Both Groups#Create Service Account User and Users#Create Service Account User allow you to customize the username and display name of a service account. Currently, the type definitions of these in Gitbeaker do not expose these options:

Steps to reproduce

gitlab.ServiceAccounts.create({
  name: "foo bar Bot",
  username: "service_account_foobar"
});

Expected behaviour

I am not supposed to get a TypeScript type error

Actual behaviour

I am getting a TypeScript type error

Possible fixes

Add the options as a type! ^^
