fix: create project with the right permission (#10485)

# Which Problems Are Solved

When a user with an `ORG_PROJECT_CREATOR` role tries to create a
project, the request fails with `No matching permissions found
(AUTH-AWfge)` error. This is because `project.write` was set as the
required permission instead of `project.create` during project creation.

# How the Problems Are Solved
By setting the right required permission (`project.create`) while
creating new projects.
