chore: extend package.json scripts for Edge and Firefox

[MikeMcC399]

Issue

package.json contains the following script definitions to start the server and run Cypress under Chrome without recording:

"e2e:chrome": "cypress run --browser chrome",
"test:ci:chrome": "run-p --race start e2e:chrome",

Equivalent scripts for Edge and Firefox browsers are missing.

Change

Add scripts:

• e2e:edge
• e2e:firefox
• test:ci:edge
• test:ci:firefox

Verification

Ubuntu 22.04.4 LTS, Node.js 20.16.0 LTS

git clone https://github.com/cypress-io/cypress-example-kitchensink
cd cypress-example-kitchensink
npm ci
npm run test:ci:edge
npm run test:ci:firefox
