Remove Legacy Sandboxes docs?

[karlhorky]

Hi, first of all, thanks for CodeSandbox and the ecosystem, it's pushed the industry to make the whole "online editor" experience very common - especially great for reproductions.

To my request:

There's a Legacy Sandboxes docs section that says:

As of Nov 20, 2023, the Sandbox editor was replaced with a new unified editor experience that blends seamlessly into the Devbox experience. Legacy sandboxes will be supported during the beta era of the new editor (until the end of 2023).

Now that it's past the end of 2023, should all Legacy Sandboxes docs and the section be removed?
