Incorrect Configuration error with testIsolation setting when experimentalSessionAndOrigin is true

[oatsoda]

Current behavior

If you have a config like this:

const { defineConfig } = require("cypress");

module.exports = defineConfig({
  e2e: {
    experimentalSessionAndOrigin: true,
    testIsolation: "off",
  }
});

Then running Cypress works just fine.

*However, if you make ANY change to the config, then you'll get an error:

Your configFile at cypress.config.js set an invalid value:

Expected e2e.testIsolation to be not set unless the experimentalSessionAndOrigin flag is turned on.

Instead the value was: "off"

You have to restart Cypress for it to work again.

Desired behavior

The error is incorrect as experimentalSessionAndOrigin is true. So it just shouldn't error.

Test code to reproduce

const { defineConfig } = require("cypress");

module.exports = defineConfig({
  e2e: {
    experimentalSessionAndOrigin: true,
    testIsolation: "off",
  }
});

The code for this is done in cypress-io/cypress#24604, but has yet to be released.
We'll update this issue and reference the changelog when it's released.
