MINOR: [Docs] Fix ARROW_USER_SIMD_LEVEL supported values (#13763)

Substitutes `SSE4.2` with `SSE4_2` in https://arrow.apache.org/docs/dev/cpp/env_vars.html#envvar-ARROW_USER_SIMD_LEVEL. See https://github.com/apache/arrow/blob/546c3771a209cbcac5e03cf26e07bcd8c9601d5a/cpp/src/arrow/util/cpu_info.cc#L443-L444 Authored-by: Andrea Giudiceandrea <[email protected]> Signed-off-by: Antoine Pitrou <[email protected]>
