[Technical review] BiDi - Add pages for new, status, and end commands of the session module

[dipikabh]

Description

This PR adds the following pages:

• session listing page
• session.new
• session.status
• session.end

It also updates:

• Modules landing page - adds basic info about how commands and events are structured
• WebDriver sidebar (webdriver.yaml)

Additional details

Since BiDi builds on capabilities and errors defined in Classic, we can share a lot of those pages between the two.
So it might make sense to move them to common location under Web/WebDriver/Reference and out of the folders under Web/WebDriver/Reference/Classic where they currently sit.

• I plan to place them directly under Web/WebDriver/Reference so that both Classic and BiDi commands can link to them.
• On the individual capability and error pages, we can note any differences in the behavior or format between Classic and BiDi.

I'll make these changes in a separate PR.

@whimboo pointed out that the top landing page https://developer.mozilla.org/en-US/docs/Web/WebDriver is also in need of an update since the addition of our BiDi section - I'll update this page along with the above structural changes.
