How to handle secure cookies when upgrading from Cypress 6 to 10

cypress-cookie-repro

Reproduction of a test failure experienced in Cypress >= 7 that does not occur in 6.

To reproduce:

1. pnpm i; pnpm test -- in the cypress UI, run the sole test (login.spec.ts). The tests will pass.
2. Change the cypress version in tests/package.json to "7^"
3. pnpm i; pnpm test. Run login.spec.ts again -- the tests will fail when, after making a successful POST to /login, the page reloads to show the user still logged out.

The failure does not reproduce without the Secure option set in the set-cookie header -- remove that, and it passes in 7.
