Shouldn't this use the @ file notation rather than a raw string, similar to the encode step above?

The idea is that since typically the JWKS is hosted on a remote server, that needs to be download over https, this allows to validate a JWT signature as a one-liner:
for example:
jwt decode $JWT_TOKEN --secret "$( curl -s https://www.googleapis.com/oauth2/v3/certs)" --alg RS256
Instead of
## first download JWKS as JSON file
curl -s https://www.googleapis.com/oauth2/v3/certs -o /tmp/jwks.json
## then validate the JWT signature
jwt decode $JWT_TOKEN --secret @/tmp/jwks.json --alg RS256
Also there is another test that uses the @./tests/pub_ecdsa_jwks.json file notation here https://github.com/mike-engel/jwt-cli/blob/main/tests/main_test.rs#L782.
