Button to show preview with this extensions disappears if other SVG extension is active

[Mart-Bogdan]

If this extension https://marketplace.visualstudio.com/items?itemName=jock.svg is active -- preview opens with that extension and this ext is ignored.

I know that this is possible, because this one https://gitlab.com/SNDST00M/vscode-native-svg-preview doesn't conflict with jock.svg

And I'd prefer to use THIS ext for preview, thanks to fact that it supports both CSS styled SVGs and live reload of preview on code change.

hi @zm-cttae thx fro fork, also can you add please "Go to source" button in "Preview only (instead of the code editor)":

like:

	context.subscriptions.push(vscode.commands.registerCommand("svgPreview.showSource", (uri?: vscode.Uri) => {
		svgPreviewManager.activePreview?.showSource(uri);
	}));
