Use manylinux2014 on all Linux builds

[jakelishman]

Summary

Numpy and Scipy are moving to drop manylinux2010 wheels on newer
platforms, which gives us some cover to do the same. To test, we need
to ensure that we pull Numpy and Scipy in binary form only (forcing pip
to install slightly older versions like 1.21 instead of 1.22 on
unsupported Python versions), rather than attempting to build Numpy from
source as part of our testing process.

Details and comments

We are going to deploy 0.19.2 with manylinux2014 for Python 3.10, since we don't have any prior commitments in the 0.19 series for Python 3.10, but we left raising the VM on other Pythons until the next minor. Given that we really don't use much of the C API, there won't be any huge improvement from upping the VM, but it'll be easier for us to keep pace with Numpy and Scipy going forwards.

I think this is implicit in cibuildwheel > 2.3 which is why I avoided upgrading it earlier. While we're updating things I think it's good to bump our cibuildwheel version too. It's fine to keep this here too though and be explicit about the version we're using, but maybe we should pull in the latest cibuildwheel release now too.

I've pushed up a new commit to bump the version of cibuildwheel, but I've left this explicit setting of the manylinux images in place. It's probably clearer for the team in general if we're explicit, rather than relying on the default behaviour.

Ready for final review. Newer versions of cibuildwheel are now tagging manylinux2010 and manylinux2014 wheels with the new manylinux_major_minor format as well (in a composite tag), which is good - that's a bit more future-proof for us.

LGTM, looking at the CI logs for linux: https://dev.azure.com/qiskit-ci/qiskit-terra/_build/results?buildId=33941&view=logs&j=8cafc477-7e80-59f4-bd23-af61455d1e35&t=c0730c84-3b34-5463-af55-a8d174d10004 everything looks correct.

When we release 0.20.0 we'll have to remember to update: https://qiskit.org/documentation/getting_started.html#platform-support to say manylinux2014 everywhere

Good point - I forgot that we now have more descriptive documentation about platform support!
