Snippet doc uses outdated version

[glennj]

Referring to exercism/roc-test-runner#30

docs/SNIPPET.txt still uses the 0.20.0 version

Hi @glennj,
0.20.0 version is the latest version of basic-cli https://github.com/roc-lang/basic-cli/releases
Did I miss something?

No, that's on me. I'm ignorant about the language. I was just checking that it didn't get overlooked.

Please close this.
