cfn submit does not work with a new version of cfn-lint

[zafodB]

The cfn-lint package is a dependency for cloudformation-cli. A new version of this package (1.3.0) was released today. Since cloudformation-cli specifies the dependency as cfn-lint>=0.78.1, the new version will be installed during a fresh installation.

This breaks the command cfn submit, with rpdk.log containing the following error message:

Traceback (most recent call last):

              ^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: module 'cfnlint.core' has no attribute 'run_checks'

When testing this, no other configuration changes have been made, other than the version of cfn-lint package.

When an older version - for example cfn-lint==0.87.7 - is (re)installed, the command works as expected.

We brought back what cloudformation-cli is depending on in cfn-lint>v1.3.1. Try to upgrade cfn-lint and try again.
