* 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.

* Added notes on bit depth for ints and floats
Added a small note about the bit depth of integers and floats in Godot's shading language as it is not explicitly stated anywhere.
The bit depth of integer and floats in GDscript and Godot's shading language are different, which can cause problems with lost precision in calculations when integers are set from GDscript as floats/ints in GDscript are 64 bits instead of 32 bits (the standard in GLSL ES 3.0).
While most are unlikely to run into problems due to this difference in bit depth, it can cause mathematical errors in edge cases. As stated by previous contributors, no error will be thrown if types do not match while setting a shader uniform. This includes GDscript floats being set as Godot shader floats (which may not be intuitive).
* Fix incorrect notice about XDG paths working on all platforms in Data paths
They are only effective on Linux/*BSD. (For reference, in most other apps,
it's rare for XDG environment variables to have an effect on other platforms.)

The space in "some times" is a mistake and should be removed as it should be one word, not two (as can be seen when it is used correctly further down the page at the start of the, "Running one-off scripts using EditorScript" section).
The phrase, "This useful for smoothing camera movement..." appears to be missing a word. It should be, "This is useful for smoothing camera movement..." instead.
- Ensure most pages are reachable through the sidebar, by removing headers on pages that are mostly indexes.
- This also means that some pages now have navigable headers again.
The new text puts the focus on the most salient reason for using GDScript. The old examples covered almost all cases (every case except for AAA games), which made for awkward wording that was not relevant to most readers. Fixes#6651
