Commit Message

provide an explicit shebang for the mypy shell script (#23479)

So, I had looked at this a few times and been curious how it worked. The
answer exposed by https://github.com/pantsbuild/pants/pull/23466 is that
it only *accidentally* worked. To quote from
https://man7.org/linux/man-pages/man3/exec.3.html:

       If the header of a file isn't recognized (the attempted execve(2)
       failed with the error ENOEXEC), these functions will execute the
       shell (/bin/sh) with the path of the file as its first argument.
       (If this attempt fails, no further searching is done.)

So on certain glibc code paths there is a `/bib/sh` fallback, but if you
just ask the Kernel to exec some "random" looking bytes it ain't gonna
work.
