VS Code extension tool check should be === not >=

[brettfo]

When the extension is installing the backing tool, the comparison should be === not >=; i.e., ensure exact version match.

@brettfo : What is the impact of this? Would this only affect customers installing a private vsix in certain niche scenarios?

That's what initially led to the discovery of this, but it's also an issue if somebody rolls back their extension to a previous version.
