ci: fix firefox group recording

[MikeMcC399]

Issue

• https://github.com/cypress-io/cypress-example-kitchensink/pull/859 introduced a grouping error for Firefox parallel tests in the .circleci/config.yml workflow. The Firefox tests are incorrectly grouped into 2x-chrome on CircleCI which causes grouping to fail due to mismatched browsers.

This can cause either the linux-test-chrome or linux-test-firefox job to fail, depending on timing. The failure also prevents the release job running.

Due to the PRs coming from a fork, recording is not tested until the PR is merged since Cypress Cloud project Id and record key are secrets.

See https://app.circleci.com/pipelines/github/cypress-io/cypress-example-kitchensink/1898/workflows/a8f38ed8-12fc-4b5f-8964-6920ca320814 for failing workflow.

Change

The Firefox tests are now correctly called with:

cypress-command: 'npx cypress run --browser firefox --record --parallel --group 2x-firefox on CircleCI'
