docs: change model to schema

[vinckr]

Related issue(s)

This PR changes the term Identity Model to Identity Schema;
capitalizing it in all instances, since it is an Ory specific term and will be documented in a glossary soon.

Changes have been made for the next and 0.7 versions.

Also changed instances of
Identity JSON Schema
Identity Schema JSON
JSON Schemas for Identities
to
Identity Model

Have tested with npm run build and found no broken links.

This commit e6d420a makes the required changes in API documentation. (Please let me know if this is the correct location).

What does the SEO say? 🤔 🦊

[vinckr]

If I search for Identity Data Model our doc is placed 2.
For Identity Schema we are in place 3 (just after ms azure docs ;) )

[vinckr]

Is there anything else I didn't consider?
We probably have to add the old
identity-data-models to https://github.com/ory/web/blob/master/static/_redirects ?

I don't know much about SEO, but changing URLs is always not as easy as just changing it.
