[Feature Request]: linter check should allow for `object_usage_linter` not being disabled

### Feature description

It appears that the linter CI detects all internal functions and imports as valid objects.

We have ignored this linter as a rule, but I believe we need it as there are unused items and even found a silent bug that would be detected by this.

I would prefer that the CI would support this _(at first glance we will probably need to install the dependencies and load package prior to lint (which will consume time and resources)_

Alternatively, we could ensure that the rule is disabled for CI, but still enabled for developers locally.

See here a run in the `teal.picks` package with linter disabled:
