update Go syntax

[hyangah]

The last update was 8months ago.

vscode/extensions/go/syntaxes/go.tmLanguage.json

Line 7 in d54d738

"version": "https://github.com/jeff-hykin/better-go-syntax/commit/302b427373ba8390786723a99f6cdf8e38833159",

Can we get it updated to pick up the fix for jeff-hykin/better-go-syntax#3 ?

I think the up-to-date version is in https://github.com/jeff-hykin/better-go-syntax/blob/master/export/generated.tmLanguage.json

Thanks for catching this! Looks like the location of the grammar changed, so I updated our grammar-updating script and pulled in the change.
