Non-standard offcanvas in Offcanvas navbar example?

[dandv]

Prerequisites

• I have searched for duplicate or closed feature requests
• I have read the contributing guidelines

Proposal

The example at https://getbootstrap.com/docs/5.3/examples/offcanvas-navbar/ seems to be using the offcanvas in a non-standard way:

• the HTML doesn't use offcanvas-end but rather offcanvas-collapse, which isn't documented at https://getbootstrap.com/docs/5.3/components/offcanvas/
• it doesn't use the data-bs-toggle and data-bs-target attributes
• the JS doesn't initialize an Offcanvas instance
• ESC doesn't close the menu

Motivation and context

It would be nice to have a navbar offcanvas example that follows the guidelines from the docs, and is keyboard-accessible.
