experimentalRunAllSpecs: Replace with new tab when selecting specs rather than closing browser

[ZachJW34]

Current behavior

When you select a new subset of specs to run with the "Run All Specs" feature, the browser closes and reopens. Not only is this not performant, it also exacerbates #21743 where the Chrome browser is unable to focus properly.

Desired behavior

Similar to run-mode, the browser should not close but rather the tab should be replaced with a new tab.

The code for this is done in cypress-io/cypress#25074, but has yet to be released.
We'll update this issue and reference the changelog when it's released.
