feat: add Groovy support

[jochil]

This change will integrate the groovy parser from https://github.com/murtaza64/tree-sitter-groovy into the project

[smacker]

@jochil the tests are failing

@smacker thanks, I messed up a go import (fixed now). But not sure if the error came from that, as happens during go get.
Locally I get no errors now:

λ go version
go version go1.14 linux/amd64

λ go get -t ./...

would be great if you can approve the workflow run again to see if the broken import caused it

[smacker]

it is probably failing because of groovy/scanner.c. The import says #include <tree_sitter/parser.h> but it should probably be ``#include <parser.h>`.

Did you use automation script? It suppose to fix it: https://github.com/smacker/go-tree-sitter/blob/master/_automation/main.go#L270

strange that this was not a problem on my local setup... but now it is working thanks.
When I ran go run _automation/main.go update groovy first, it was not doing anything as the commit sha in the grammars.json was already the HEAD one. But switching back to an old version and let the script do the import worked just fine

[smacker]

thanks
