REST API: Check for WP5.5 and skip registering routes

[mkaz]

Description

The Image Editor routes are included in WP 5.5, so do not need to be registered in the plugin. This change adds a check and only registers if the version is less than 5.5

How has this been tested?

Use WordPress 5.4.x and the Gutenberg plugin and confirm the routes load as expected.
Use WordPress 5.5-beta+ and the Gutenberg plugin and confirm the routes are loaded from core and not the plugin.

Types of changes

Adds a logic check for version around the route registration using PHP's version_compare function.

Thanks! I haven't tested but left a bit of feedback.

I tested this by echoing some output in the endpoint response from Gutenberg. It handles the response with WordPress 5.4. When I upgraded to WordPress 5.5 beta, the core endpoint handled the response.

Seems to work as expected. Thanks!
