[REFACTOR] :recycle: change routes for users: `markadmin` and `markverified`

[aayushchugh]

Description

Currently we are using these routes

Mark user as admin --> PATCh /api/admin/users/markadmin/:id
Mark user as verified --> PATCH /api/admin/users/markverified/:id
Get all users --> GET /api/users
Update Username --> PATCh /api/users/:id
Delete user --> DELETE /api/admin/users/:id

we can change the routes of markadmin and markverified to follow conventions eg:-

Mark user as admin --> PATCH /api/admin/users/:id/markadmin
Mark user as verified --> PATCH /api/admin/users/:id/markverified

Anything else?
