parallel-group-params-mismatch caused by osVersion

[johnpolacek]

Similar to #7199 we are running into an issue where we hit the parallel-group-params-mismatch error, in this case due to a mismatch in osVersion. This happens when Github Actions rolls out an update - see https://github.com/actions/virtual-environments/issues/2505#issuecomment-764001469

Is there anything that can be done to avoid this?

Would love to know how to get around this.

The workaround was added to the documentation https://github.com/cypress-io/github-action#parallel some time ago:

During staged rollout of a new GitHub-hosted runner version, GitHub may provide a mixture of current and new image versions used by the container matrix. It is recommended to use a Docker image in the parallel job run which avoids any Cypress Cloud errors due to browser major version mismatch from the two different image versions. A Docker image is not necessary if testing against the default built-in Electron browser because this browser version is fixed by the Cypress version in use and it is unaffected by any GitHub runner image rollout.
