Registered kernel spec name does not match the name served by jupyer-server

[trungleduc]

Description

The spec registered by the extension uses xeus-python as the kernel name, but in JupyterLab, the kernel name served by /api/kernelspecs is xpython. The mismatch makes Voici can not find the correct kernel for a notebook saved by JupyterLab

xeus-python-kernel/src/index.ts

Lines 30 to 37 in 71e105d

	spec: {
	name: 'xeus-python',
	display_name: 'Python (XPython)',
	language: 'python',
	argv: [],
	resources: {
	'logo-32x32': logo32,
	'logo-64x64': logo64
