misc: update playwright-webkit from 1.24.2 to 1.56.1 and base-internal image from Debian Bullseye to Debian Trixie

[AtofStryker]

• Closes WebKit 26 fails driver-integration-tests-webkit (cookies.cy.js) #29973
• Closes Update WebKit testing to 26.x #29954
• Closes Update the CircleCI executors to use a newer cypress/browsers-internal image #30392

Additional details

Updates WebKit to version 26 as previous versions are no longer available. There are some behavior changes with the update, some which are commented on the PR.

It looks like there is some cookie ordering inconsistencies between the linux/mac builds of webkit. In order to make this consistent, we check for a strict domain match when running getCookie and if no match is found, we then fall back to the apex domain.

Additionally, now that we are updating WebKit, we can now update from Debian Bullseye (Debian 11) to Debian Trixie (Debian 13). The cypress-docker-images PR to add trixie base-internal images is cypress-io/cypress-docker-images#1440

Steps to test

How has the user experience changed?

PR Tasks

• Have tests been added/updated?
• Has a PR for user-facing changes been opened in cypress-documentation?
• Have API changes been updated in the type definitions?

Note

Upgrades WebKit (playwright-webkit) and switches CI/Docker images to Debian Trixie, adding strict-domain cookie matching with apex fallback and updating tests/changelog accordingly.

• WebKit / Cookies:
  • Update playwright-webkit to 1.56.1 (and lockfile).
  • Implement strict-domain cookie matching in cookieMatches() (optional { strictDomain: true }).
  • webkit-automation: getCookie() first matches exact domain, falls back to apex; normalize cookie props unchanged.
• CI/CD & Docker:
  • Migrate base images from Bullseye to Trixie: new anchors base-internal-trixie, base-internal-yarn-berry in .circleci and image refs in docker-compose.yml and system tests.
  • Minor pipeline comment fix regarding Debian 11 glibc note.
• Tests:
  • Add unit tests for strict domain matching; adjust cookie tests (stable sorting) and system test image refs.
• Docs/Changelog:
  • Changelog: WebKit now prefers fully qualified cookie domain, falls back to apex.
  • Electron upgrade doc: update image name examples to -trixie.

• Did you consider V8 Snapshot build failure on newer Linux OS like Debian 13 #32192 ? Would this be a barrier to updating to Debian 13 trixie?

@MikeMcC399 I don't think for the cypress-io/cypress jobs this is a blocker but could be wrong, but it's likely a blocker when we build the binary. Going to confirm with @ryanthemanuel.

@AtofStryker Question around whether this requires a changelog entry.

[AtofStryker]

@MikeMcC399 it looks like the v8 snapshot issues are a runtime issue and not a build issue and doesn't appear to block building of the binary, so this should go ahead and work, though it doesn't close #32192
