Revert requirement of tensorflow-macos package for MacOS platforms

[marygiotandoi]

Hi,

In a previous PR, tensorflow-macos was added as a dependency to enable installing newer versions of tensorflow-recommenders on MacOS-machines, as the package requires tensorflow >= 2.9.0 and at that time it did not exist for macos. This was included in the 0.7.3 release.

With TensorFlow 2.16.1, Apple Silicon users are now advised to install TensorFlow via pip install tensorflow. Due to this change, installing the latest tensorflow-recommenders via poetry fails with a dependency error (Package 'tensorflow-macos' is listed as a dependency of itself), as reported in issue #713.

This PR reverts the changes from PR #549 to resolve the issue.
