Bump MSRV to 1.61 and all rust dependencies to latest releases (#9393)

This commit bumps the minimum supported rust version from 1.56.1 to
1.61.0 (which is the LCD for all our dependencies) which was released
on 2022-05-19. By doing this we're now able to bump all of our
upstream dependencies to use the latest releases.

+    The minimum supported Rust version (MSRV) has been increased from 1.56.1
+    to 1.61.0. If you're are building Qiskit from source you will now need to
+    ensure that you have at least Rust 1.61.0 installed to be able to build
+    Qiskit. This change was made as our upstream dependencies have increased
+    their MSRVs.
