Maintenance Release

Compatibility

• Require GPyTorch>=1.15.2 and linear_operator>=0.6.1 (#3182).

Bug Fixes

• Fix BAxUS bugs (#3204).
• Fix q-dim bug in ScalarizedPosteriorMean (#3191).
• Project candidate_set in qMultiFidelityMaxValueEntropy.__init__ before
  passing to super().__init__, allowing candidate_set to be either n x d
  (without fidelity dims) or n x (d + s) (with fidelity dims) (#3205).

Other Changes

• Make d and target_fidelities required arguments in
  project_to_target_fidelity to eliminate silent bugs (#3203).
• Add test harness infrastructure for acquisition function testing (#3190, #3192).
• Fix typos and docstring issues across botorch (#3211).
• Fix docstring issues in analytic acquisition functions (#3208).
