also building and publish aarch64 linux wheels

Such that the folks that run linux on ARM machines can sing your praises.

+1 on this — we need aarch64 wheels for AWS Lambda Graviton deployments.

One thing I noticed: in pypi-release.yml, the new matrix entry defines CIBW_MANYLINUX_AARCH64_IMAGE and CIBW_ARCHS_LINUX as matrix variables, but the env: block of the build step doesn't pass them through to cibuildwheel (unlike test-and-build.yml where they are correctly added). The release build would fall back to cibuildwheel's defaults, which may work in practice but is inconsistent with how x86_64 is handled.

I've put up a version with that fix at kkilchrist/pyahocorasick@add-aarch64-wheels if helpful.

Thanks @wilko77 @kkilchrist for your inputs, I've made some more changes and added this through #217 and https://github.com/WojciechMula/pyahocorasick/releases/tag/v2.3.1 this would also be released to pypi soon.
