[vscode] Fix package.json path parsing issue

Summary:

Ran into trouble when attempting to package the vscode extension due to errors parsing the logo path.

Running vsce package locally resulted in the following error:

ERROR The specified icon 'extension/./static/Logo.png' wasn't found in the extension.

This diff attempts to fix that.

Test Plan:

vsce package and installed locally
