Run schemars test from extra_tests

We have a mechanism to run additional custom tests by way of the
`extra_tests.sh` script in each crate.

Remove the CI job and run the schemars test using `extra_tests.sh`. This
patch changes the test coverage because currently the schemars test is
only run with a stable toolchain but with this patch applied it runs
with stable, MSRV, and nightly.

Fix: #2787
