* Update gdscript_exports.rst
Added hyperlinks for each export type that lead to annotation documentation further explaining each export type, as requested in issue#9281
* Update physics_introduction.rst
The docs page for raycasting provides a link to the physics introduction page for how to set a collision mask on a raycast created in code. The physics introduction page does not mention export annotations for exporting a collision mask. This pull request adds a brief bit about exporting layer masks, and links to the export annotation docs.

The code example demonstrating the usage of the "or_greater" and "or_less" hints for the export_range annotation does not declare a variable after the annotation, which is inconsistent with the previous three code examples in the section.
Also, giving the export_range a step of 1 does not create a slider for the property in the editor, like the text suggests, but it instead creates a spin box. The step should be changed to a float so the property can appear as a slider.
`AnimationNode`'s inherited classes are `Resource`, `RefCounted`, and `Object`.
I assume it meant to say "derived classes", or something along the lines of
"and all classes which inherit it".
This PR changes the "export"s in the Array section of the GDScript Exports documentation to the "@export" annotation to be in line with 4.0.
Also slightly touches up the wording when referring to default null assignment and Packed*Arrays.
