feat: Remove Studio as experimental - Turn Studio Beta on for all users of Cypress (no need for config flag)

[mabela416]

• Closes
  Studio: Remove experimentalStudio configuration, make default behavior for all users of E2E tests #30997

Additional details

Remove the experimentalStudio configuration option and turn on Cypress Studio Beta for all users when in end-to-end testing.

Remove the configuration option
Remove any types around the config
Remove any internal use of the configuration in the repo
Remove any tests around the flag
Display a warning message to users when this config option is used - informing them that it's safe to remove this configuration option. See similar warnings in code

Steps to test

• Set the experimentalStudio: true in your project's cypress.config.js then open your project in the app. In the terminal, you should see a warning about being able to safely remove the experimentalStudio config.

How has the user experience changed?

Note

Enables Cypress Studio by default for E2E, removes the experimentalStudio config, and updates UI, config, errors, tests, and docs accordingly.

• Studio (E2E) enabled by default
  • Remove dependency on experimentalStudio across app runner and reporter; studioEnabled and Studio button logic no longer read the flag.
  • Initialize Studio lifecycle when not in text terminal and testing type is e2e.
• Config/Errors
  • Remove experimentalStudio from public options and defaults; add breaking warning EXPERIMENTAL_STUDIO_REMOVED with messaging.
  • Update GraphQL schema enums and snapshots to reflect removal.
• Tests/Fixtures
  • Delete tests and config mutations that toggle experimentalStudio; adjust E2E specs to new default behavior.
  • Update unit/system test snapshots for removed option.
• Docs/Locales/Changelog
  • Update Studio dev guide to not require the flag; remove Studio experiment strings from locales.
  • Changelog: add note that Studio is available by default and minor date format fix.
• Configs
  • Remove experimentalStudio from internal cypress.config.ts files (driver/reporter/app).

@mabela416 Just some wording updates.

Manually tested that this works.

Not understanding why all the percy snapshots are off. Seems like a quirk with them?
