🐞Replace package_available with module_available

[harimkang]

📝 Description

This PR replaces package_available with module_available from the lightning-utilities package.

• package_available: This function does not check that the actual import works; it simply checks whether the spec for that package exists. Passing this may actually cause an error on import depending on environment.
• module_available: This checks to see if the actual import will work.

Due to the above differences, anomalib install is currently not running.

How I discovered this issue:

pip install -e .
anomalib install

To use other subcommand using `anomalib install`
