fix: patch new tab creation for firefox 124 and up to fix issue where…

[AtofStryker]

… cypress was not executing beyond the first spec in cypress run (specific to firefox).

• Closes Only first test runs with Firefox 124.0 #29172

Additional details

This PR addresses an issue with Firefox versions 124 and up where the browsers.tabs extension API behavior changed.
Previously, in versions of Firefox 123 and below, removing all tabs in the browser would result in a new tab being created. Now, in Firefox versions 124 (and beta 125 as well), this behavior no longer happens. Instead, the browser closes, but the process is still running. Cypress cannot find a tab to connect to, and therefor browser connection times out when running the second spec in run mode with npx cypress run -b firefox.

To fix this, this PR creates an about:blank tab (but does not active it) before all the other tabs are removed. This tab is the only remaining tab, which is fairly consistent with the behavior we saw previously in Firefox 123 and lower.
