ci: fixed workflow for generating introspection query for docs

[banasa44]

Description

In this PR two problems are fixed:

1. We have now 2 processes that generate 2 different types of introspection-query for subgraph schema. Some modifications need to be done for the introspection for docs purposes. Create a temp schema, add some necessary lines for the introspection-partial, generate it, and delete the temp.schema.
