Update package lock (#1003)

* Add leniency in how positions are handled

Previously, positions with end column of 0 were rejected by the
extension. CodeQL positions are supposed to be 1-based, but the CLI
does handle 0-based and negative positions by using character offsets
from the current line start.

Instead of rejecting these kinds of positions, the extension should
handle them as gracefully as possible.

Fixes #999
