* Skip removed grammar submodule
* Clean up old grammar from grammars and grammars.yml
* Clean up unused grammar license
Run `script/licensed`.
This was missing change in 12f9295 of #3350.
* Clean up license files when we replace grammar
Update license files by running `script/licensed`.
Since we replace grammar, the old grammar license must be removed
and new grammar license must be added.
* Remove trailing spaces
* Setup Bundler in some scripts
* Update grammar index
* Make prune-grammars script to be callable in a script directory
* Prune unused xquery grammar repo
source.xq by language-jsoniq is actual tm_scope for XQuery.
* Remove xquery submodule
git submodule deinit vendor/grammars/xquery/
git rm vendor/grammars/xquery/
* Fix invocation of script/list-grammars
This fixes#3339.
* Make add-grammars script to be callable in a script directory
* Generate samples.json before running list-grammars
list-grammars requires linguist.
