Fix nightly workflow again

[agriyakhetarpal]

Description

From #879 and #883: TIL that uv pip does not accept -y for "yes", it installs/uninstalls without prompting the user for input. This was missed when I changed pip to uv pip in the "latest" nightly tests.

Type of change

Please add a line in the relevant section of CHANGELOG.md to document the change (include PR #).

Important checks:

Please confirm the following before marking the PR as ready for review:

• No style issues: $ pre-commit run or $ nox -s pre-commit (see CONTRIBUTING.md for how to set this up to run automatically when committing locally, in just two lines of code)
• All tests pass: nox -s tests
• The documentation builds: nox -s doctest
• Code is commented for hard-to-understand areas
• Tests added that prove fix is effective or that feature works

Side note: we shouldn't install the dev dependencies alongside all. Instead, we should use the newer dependency groups. I'll prepare a PR for this (edit: did that with #885).
