Bump pypa/cibuildwheel from 4.1.1 to 4.2.0

[dependabot]

Bumps pypa/cibuildwheel from 4.1.1 to 4.2.0.

Release notes

Sourced from pypa/cibuildwheel's releases.

v4.2.0

• 🌟 CPython 3.15 wheels are now built by default - without the "cpython-prerelease" enable set. It's time to build and upload these wheels to PyPI! This release includes CPython 3.15.0rc1, which is guaranteed to be ABI compatible with the final release. (#2944)
• ✨ Adds Pyodide 3.15 support with the cp315-pyodide_wasm32 build identifier, using Pyodide 315.0.0a2. These are also stable wrt. the final release. (#2958)
• 🐛 Retries a failed download six times with exponential backoff, so short network outages no longer stop a build. A 4xx response is still reported at once. (#2953)
• 🐛 Accepts default as a build-frontend value on Pyodide, and accepts pyodide-build in the top-level table and in overrides (#2951)
• 🛠 Holds pip back on GraalPy, where newer pip breaks the build (#2955)
• 🛠 Updates Pyodide to 314.0.4 (#2949, #2952)
• 🛠 Updates dependencies and container pins (#2952, #2960)
• 💼 Updates CI action pins (#2948, #2954)
• 🧪 Uses pp311 for the abi3 test, and deletes test_overridden_pip_constraint, which is not necessary since #2583 (#2956, #2957)

Footnotes

1. 86 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

2. No successful run was found on 3.15 (ffb8405) during the generation of this report, so b9ff891 was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩
