What does this PR do?
Removes the
typescript@5sandbox pins from Cypress and Playwright integration tests so they use the default TypeScript version again.Fixes the TypeScript 6 compatibility issues that required the pins:
.cy.tssource-line tests write a spec-local TypeScript config for Cypress' webpack preprocessor, with TS 6 deprecation handling gated by the installed TypeScript version.Motivation
PR #7932 bumped the default TypeScript test dependency to 6.x, but Cypress and Playwright integration tests were pinned to TypeScript 5 because TS 6 changed emitted output and type/config behavior. This removes that temporary workaround and keeps the tests exercising the default sandbox dependency.
