Use template_release on linux to fix a crash with release exports

[guillaumeriousat]

Fixes issue this issue #42

Modifies the .gdextension file to use template_release when exporting a project in release mode on linux.

Also adds linux template_release builds to the CI.

The sample app now displays an image in release mode before crashing. It also crashes in debug mode so I think its a separate issue.

Thanks for catching this!

If I remember correctly, the only reason I even have the CI build target_debug is so that I don't have to change the .gdextension during testing. The CI builds them with debug_symbols=no optimize=speed lto=auto, so it's probably very close to a target_release binary.

Is the issue caused by loading a target_debug binary for release, or by not specifying a specific binary for to use for linux.release?

I'd say, let's take it opportunity and do it proper for all platforms!

perhaps like so?

	target-type: [template_debug]
	target-type: [template_release, template_debug]

Suggested change

	# Only build template_release on linux. release mode template exports can't use
	# template_debug on linux but can on other platforms.
	include:
	- target:
	platform: linux
	arch: x86_64
	os: ubuntu-22.04
	target-type: template_release
	float-precision: single
	- target:
	platform: linux
	arch: arm64
	os: ubuntu-22.04-arm
	target-type: template_release
	float-precision: single

This would be covered by adding template_release to the matrix. Results in template_release and template_debug being built for all platforms.

	windows.x86_64.single = "bin/windows/libgodot-ndi.windows.template_debug.x86_64.dll"
	macos.single = "bin/macos/libgodot-ndi.macos.template_debug.universal.dylib"
	windows.x86_64.single.debug = "bin/windows/libgodot-ndi.windows.template_debug.x86_64.dll"
	windows.x86_64.single.release = "bin/windows/libgodot-ndi.windows.template_release.x86_64.dll"
	macos.single.debug = "bin/macos/libgodot-ndi.macos.template_debug.universal.dylib"
	macos.single.release = "bin/macos/libgodot-ndi.macos.template_release.universal.dylib"

My understanding is that the issue is caused by loading a target_debug binary with a release export on linux. The .so file seems to be found when executing the export but it then crashes.

My changes were targeted to linux only because I assumed you would want to leave the other platforms as is but I agree that the changes you have proposed are more straightforward. I'll update my PR later today !
