lfortran not recognized on windows-latest

[minhqdao]

Tried running fpm test with the configuration windows-latest + lfortran + 0.33.0 and got:

 + mkdir build\dependencies
[  0%]                      run_f.f90
[ 12%]                      run_f.f90  done.

'lfortran' is not recognized as an internal or external command,
<ERROR> Compilation failed for object " src_run_f.f90.o "
operable program or batch file.
<ERROR> stopping due to failed compilation
STOP 1
Error: Process completed with exit code 1.

See note in readme

Note: LFortran is currently only discoverable by name with bash on Windows, see #57 (comment).

If you find a solution a patch would be very welcome.
