Use `assertAlmostEqual` in `BloomEmbeddingTest.test_logits`
# What does this PR do?

`BloomEmbeddingTest.test_logits` currently uses `assertEqual` to compare 2 floats. We should instead use `assertAlmostEqual`.

Currently we don't see this test failing. However, with different PyTorch versions, we might get test failure - this happens for Past CI (PyTroch 1.10), where we got
```bash
AssertionError: 1.9311904907226562e-05 != 1.9431114196777344e-05
```
