What happened?

While migrating conda environments from Oracle Linux 7 to Oracle Linux 8, we hit the following error:

./conda-unpack 
env: 'python': No such file or directory

The generated conda-unpack script uses the following shebang #!/usr/bin/env python Linux distributions discourage the use the unversioned python.

Could we generate the conda-unpack script to use the following shebang ?

#!/usr/bin/env python3

which is a standard way to do it
