Migrate manywheel and conda Docker build from centos:7 to pypa/manylinux2014_x86_64

[atalman]

We would need to migrate our Docker builds to later version of centos:7 since its approaching end of life in 1 year.

CentOS-7 updates until June 30, 2024: https://wiki.centos.org/FAQ/General#What_is_the_support_.27.27end_of_life.27.27_for_each_CentOS_release.3F

Following Docker builds: https://github.com/pytorch/builder/blob/bb821d4afed1b7ce9a2fd2ee043d173cde2dfd5c/manywheel/Dockerfile#L5 https://github.com/pytorch/builder/blob/bb821d4afed1b7ce9a2fd2ee043d173cde2dfd5c/conda/Dockerfile#L3 https://github.com/pytorch/builder/blob/bb821d4afed1b7ce9a2fd2ee043d173cde2dfd5c/manywheel/build_docker.sh#L20 ...

Hence we should migrate to: https://quay.io/repository/pypa/manylinux2014_x86_64?tab=tags&tag=latest as @malfet suggested

But centos:8 already EOLed in 2021, see https://www.centos.org/centos-linux-eol/ IMO we should migrate Linux docker base to https://github.com/pypa/manylinux / https://quay.io/repository/pypa/manylinux2014_x86_64?tab=tags&tag=latest
