For the WriteAuthorizationModel snippet, use the DSL and only show the CLI

[rhamzeh]

For this component: https://github.com/openfga/openfga.dev/blob/main/src/components/Docs/SnippetViewer/WriteAuthzModelViewer.tsx

Remove all except the CLI

And for the CLI, echo the model DSL into a temp file and have the CLI write that file

What does it mean "And for the CLI, echo the model DSL into a temp file and have the CLI write that file"? Would we tell them to do that? would the snippet include echo "..." > file?
