test(sampling): unflake unsupported char tests

[KowalskiThomas]

Description

https://datadoghq.atlassian.net/browse/PROF-15927

test_rule_init_via_env_service_pattern_contains_unsupported_char was flaky. This fixes the issue by forcing _raise=True inside each test's own override_global_config(...) so the assertion's precondition is guaranteed regardless of test ordering or ambient global state.
