"git bisect visualize" stopped running "gitk" on Git for Windows
when the command was reimplemented in C around Git 2.34 timeframe.
This has been corrected.

* ma/locate-in-path-for-windows:
  docs: update when `git bisect visualize` uses `gitk`
  compat/mingw: implement a native locate_in_PATH()
  run-command: conditionally define locate_in_PATH()
