Update re2 to 2023-02-01 to resolve compilation errors with new musl toolchain:

  /home/runner/work/cross/cross/target/tmp/tmp.NPKdi1BWoT/re2/util/pcre.h:503:11: error: 'int32_t' does not name a type
    503 |   mutable int32_t     hit_limit_;      // Hit limit during execution (bool)
        |           ^~~~~~~
