make_release.sh does not work

[tristanbiesecker]

When running make_release.sh from a cloned repo like so sh dist/make_release.sh, or the mojo command directly mojo package ./stdlib_extensions -o ./dist/stdlib_extensions.mojopkg, I get the following error:

+ mojo package ./stdlib_extensions -o ./dist/stdlib_extensions.mojopkg
