docs(readme): update sequenced api example

[code-forger]

Motivation and Context

The sequenced api example resulted in multiple calls from the 'second' api in the sequence, these api calls were malformed, as the input required from the 'first' api in the sequence was not available yet.

How Has This Been Tested?

Locally in a module
