Port to Godot 4

[OmarShehata]

Updates this add on for Godot 4 (#5). This is NOT backwards compatible, so not sure if we'd want to restructure the repo to have a godot4 folder? Or just make the Godot 4 the canonical one and keep the 3.x version on a branch?

See the 4.0 ported demo project here: godot-extended-libraries/godot-antialiased-line2d-demo#1

90% of the changes here are just the 3.x -> 4.x syntax. One thing I had to add was explicitly setting the texture filter:

texture_filter = TextureFilter.TEXTURE_FILTER_LINEAR_WITH_MIPMAPS

I'd follow the Godot policy, which is to use master for 4.x and a 3.x branch for 3.x. So this PR can be merged directly in master, and I'll create a 3.x branch with the last commit before this PR.

This update to your previous plugin is clearly what I have been looking for... but I'm having an awful time figuring out how to download it. I'm a bit of a beginner and I still find Git very confusing. Do you have plans to make this update available in the official Godot asset library? or is there a place that I can download a .zip?

For future reference, you can get there by clicking the branch name at the top of the pull request (OmarShehata:master here), clicking the green Code button on the fork's repository page, then Download ZIP at the bottom of the popup.

Thank you so much! And for the 'how to' too!

[OmarShehata]

ah I forgot about this, I can push that suggested change soon so that this can be merged so it's easier for anyone else who needs this for godot 4 and/or so people can contribute!

[Calinou]

Merged manually with ccfc40a. Thanks!

The asset library update will follow soon (it'll be a new asset so the 3.x version remains readily available).
