Update blender_manifest.toml to comply with Linux arch
See docs https://docs.blender.org/manual/en/latest/advanced/extensions/getting_started.html
Fix #138. https://docs.blender.org/manual/en/latest/advanced/extensions/getting_started.html shows that the correct value should be linux-x64
works for me.
unfortunately looks like plugins need to match the exact python minor version installed so this doesnt work anyway with python 3.13
@aep the Python minor version incompatibility is sort of an upstream bug. In theory maintainers can bundle all Python sub versions in a single package (and make the package very bloated), but ideally separate packages are created. See this https://projects.blender.org/blender/blender/issues/127090 for details.
