[Browser Isolation] Rename canvas rendering to Canvas Remoting (#30034)
* [Browser Isolation] Rename canvas rendering to Canvas Remoting Replace 'canvas rendering' with 'Canvas Remoting' throughout the documentation to match the updated UI labels. Rename the MDX file, image file, and add a redirect from the old URL. * fix: move redirect to static section (before dynamic redirects)

Canvas rendering is a Browser Isolation capability that optimizes performance for web applications using the HTML5 Canvas API (a browser feature that allows web applications to draw graphics directly on the page). It sends vector draw commands to the client instead of rasterized bitmaps (pixel images), reducing bandwidth consumption and improving frame rates for productivity applications.

## How it works
1717

1818
Browser Isolation uses Network Vector Rendering (NVR) to send lightweight drawing instructions to the user's browser, rather than streaming rendered pixels or video of the page. However, HTML5 Canvas content previously required server-side rasterization (converting draw commands into pixel images), sending large bitmaps for every frame.
