LOG: [dataflow][nfc] Fix u8 string usage with c++20 (#84291)

Clang returns an error when compiling this file with c++20
```
error: ISO C++20 does not permit initialization of char array with UTF-8 string literal
```
It seems like c++20 treats u8strings differently than strings (probably
needs char8_t).
Make this a string to fix the error.
