REST API schema docs should be updated with new formats introduced in WP 5.9

[jonwaldstein]

Issue Description

As of WordPress 5.9 there are new options for the format param including text and textarea.

These are important for string types because without specifying a format, strings do not get sanitized properly.

• https://developer.wordpress.org/rest-api/extending-the-rest-api/schema/#changelog

Why is this a problem?

When utilizing the REST API with json schema, it is really handy to know the format options that help with sanitization, particularly for string fields.

Suggested Fix

Changelog

https://developer.wordpress.org/rest-api/extending-the-rest-api/schema/#changelog

We should add 5.9

WordPress 5.9

• Support the text-field and textarea-field formats.

In this section

we should add:

• text-field a text field
• textarea-field a textarea field

It would also be good to mention how by adding these formats it will also take care of sanitization.
