Make the steps for deploying to Meta Quest 2 (and other Android headsets) clearer

[dsnopek]

This PR is attempting to specifically address the points of confusion from godotengine/godot#78427

Namely:

• Making it extra clear that you need to follow most of the normal Android setup steps before doing the things on the OpenXR-specific page.
• Changing one of the screenshots to have the "Use Gradle build" checkbox checked (as described in the text instructions, but confusingly shown unchecked in the original screenshot)
• Specifically linking to the "One-click deploy" documentation, and making it clear that developers may need to perform some extra steps from their headset vendor's documentation in order to make it work. And I added a note and link for the Meta Quest in particular, since it's the most popular headset.

I also fixed some terminology that I think is incorrect: "export template" -> "export preset"

Looks good!

I would maybe add a screenshot of the dropdown and option to run, I could create one for you to use that shows both Quest and Pico in the menu to make clear why it is a dropdown.

Thanks :-)

Yeah, that'd be awesome! Personally, I only have various flavors of Quest

@dsnopek you'll need to crop it and probably convert it to webp, but hopefully this helps?

[dsnopek]

Thanks so much, @BastiaanOlij!

I cropped Bastiaan's screenshot and blurred the areas behind the dropdown (since they are pretty distracting), converted to webp and added to the new section about one-click deploy.

Hopefully, the blur is an OK way to do this? I could also just cut those parts out, but I worried that that could be confusing since there is stuff there and might it make it hard for folks to find the right part of the screen.

For a image like that where you want to direct people to a specific part you would add an outline instead of blurring the background. Like this:
android_one_click_deploy.zip

And if you don't mind please update your PR with that image.

[dsnopek]

Sure! I've updated the PR, replacing the image with yours. Thanks for making it :-)

[BastiaanOlij]

lgtm, nice work!

Thanks!
