FakeProviderForBackendV2.get_backend raises an error when filtering by name

[mberna]

Environment

• Qiskit Terra version: 0.21.0
• Python version: 3.10.4
• Operating system: macOS Monterey

What is happening?

I'm getting a TypeError when trying to get a backend by name using FakeProviderForBackendV2.get_backend

TypeError: 'str' object is not callable

How can we reproduce the issue?

Code:

from qiskit.providers.fake_provider import FakeProviderForBackendV2

provider = FakeProviderForBackendV2()
backend = provider.get_backend('fake_almaden_v2')

Output: TypeError: 'str' object is not callable

What should happen?

The provider should return the corresponding fake backend.

Any suggestions?
