Only show warning box if page is outdated

[tetrapod00]

Additionally, changes the color of the warning box from green (tip colored) to orange (warning colored), which closes #7196.

Looks like this:

We no longer display this admonition declaring the page up to date:

There are 46 of these outdated pages remaining.

(Originally, this PR only color-coded the boxes as the linked issue asks for.)

Approving, although I'm wondering whether now that the dust has mostly settled, we should just have the "this page is outdated" one - a page not being outdated should be the expected state if there's nothing mentioned, after all?

This was different once when nearly everything was outdated due to Godot 4 being heavily WIP. It may even help a little bit with the notice-boxes-everywhere issue.

100% in favor of no longer displaying the Up to date boxes, and only displaying the Work in progress ones. I figured that was already the plan, but the threshold for doing so was a smaller number of remaining outdated pages - 20? 10? 0? All the pages in #5121 being done?

The docs being generally up to date is expected behavior, and displaying a box to say that a page is up to date adds clutter to the page.

The continued existence of the Up to date box, and the fact that the text includes a minor version, implies a level of QA that frankly doesn't exist. We are not going over every page in each minor version to verify that it is "up to date for Godot 4.4". Instead, we at some point went over the page to verify that it is up to date for Godot 4.0.

The one point in favor of the Up to date boxes remaining is that it's another place that asks the reader to contribute if they see something wrong. But I don't think that's enough.

Pushed an update to remove the Up to date box. (Once that's firmly approved I'll squash and update the PR)

LGTM. Considering the time of the year, I'm going to leave this open for a bit so others can still chime in.

Edit: for posterity, we already have thumb ups on this on RC from Mickeon, PatrickFlameLizard, Akien and Emi.

❄️ I think we have enough consensus to go ahead with this. Thanks everyone, and thanks tetrapod :)
