Augmented assignment on a list with a tuple value doesn't work

[tristanlatr]

Steps to reproduce

import astroid.helpers

def test_astroid_augmented_assigment_list_and_tuple() -> None:
    mod = astroid.parse('''
    l = []
    l += (1,2)
    ''')

    assignment, augmented_assigment = mod.getattr('l')
    assert astroid.helpers.safe_infer(augmented_assigment).as_string() == '[1,2]'
    # We get AssertionError: assert Uninferable == '[1,2]'

Current behavior

We get AssertionError: assert Uninferable == '[1,2]'

Expected behavior

The provided test should pass.
If one can point me to the right direction, I can try to provide a PR for the fix.

python -c "from astroid import __pkginfo__; print(__pkginfo__.version)" output

2.12.12

This is probably part of the AugAssign path. Checking out infer_augassign might help, but I worry that this might be a difficult to fix bug.
