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

[averissimo]

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:
