✨ Add Amazon Braket devices

[flowerthrower]

Problem Statement

Amazon Braket provides a variety of QPUs. In order to keep the MQT Bench devices state-of-the-art, it would be nice to include those more recent devices. Ideally, the new devices come with current data on qubit fidelities and gate errors, as enabled by this PR.

Proposed Solution

The qiskit-braket-provider can be used to simply import the devices as Qiskit Target, which is already compatible with MQT Bench's circuit creation. Afaik: The Amazon API requires a user-account / key to access the device data. It would be nice if a user could simply specify their access token, but ideally (since we don't want to execute any circuits), the device selection should work without one.
