prevent unsupported locale setting error in GHA

related to https://github.com/ansible/ansible/pull/78175

the way the GHA runner is built, Python runs with a mixed locale between the FS bits and the default encoding, which can cause unpredictable issues

adding env var `LC_ALL: "C.UTF-8"` prevent flakiness due to locale issue
