How to split specs if the user has used cypress run --spec ... parameter? Related to https://github.com/cypress-io/cypress/issues/26032

Probably can replace --spec ... with --config specPattern=... equivalent

Can confirm that simply replacing --spec with --config specPattern= equivalent works.

Replaced --spec \"tests/cypress/integration/**/*_spec.*\" with --config specPattern=\"tests/cypress/integration/**/*_spec.*\"

And everything worked as expected.
