Make sure Git for Windows' bash.exe is found in the PATH

This provides the convenience that after this Action, a regular Bash
task will use Git for Windows' SDK's Bash:

	- shell: bash
	  run: uname -s

This will run in Git for Windows' SDK and therefore report something
like this:

	MINGW64_NT-10.0-19042
