[LTP] [PATCH v3 2/2] Add centos10 to test matrix

[Li Wang]

Hi Petr, Siddhesh,

Siddhesh's words make sense, but considering we (RedHat) already test
Fedora-ELN [1] internally with the LTP latest branch, so it's not necessary
to enable CentOS-10 stream in GitHub CI again.

[1] Acts as a testing ground for RHEL's next major version (e.g., RHEL 10).

@Siddhesh, you can find the Fedora-ELN test in CKI system, which plays
an important role in testing LTP master branch.
