Update psutil dependency from ^5.9.4 to ^7.0.0

[RubelMozumder]

Summary

The current psutil version constraint in pyproject.toml is ^5.9.4, which pins to the 5.x series. psutil has since released a 7.x major version, and it would be beneficial to update the constraint to ^7.0.0 to allow users to benefit from the latest improvements and fixes.

Proposed Change

# Before
psutil = "^5.9.4"

# After
psutil = "^7.0.0"

Testing

I have run the full test suite after updating the constraint to ^7.0.0 and all tests passed successfully without any issues.

Please consider merging this update at your convenience.

@dineshpinto, any plan to tackle this issue? This issue is very simple, just need to upgrade the version of psutil, that's it.
