fix: go module path

[kitagry]

When I use the Go bindings, I get the following error.

$ go get github.com/takegue/tree-sitter-sql-bigquery/bindings/go
go: downloading github.com/takegue/tree-sitter-sql-bigquery/bindings/go v0.0.0-20250126192726-c0c4f0ed7b87
go: github.com/takegue/tree-sitter-sql-bigquery/bindings/go@upgrade (v0.0.0-20250126192726-c0c4f0ed7b87) requires github.com/takegue/tree-sitter-sql-bigquery/bindings/go@v0.0.0-20250126192726-c0c4f0ed7b87: parsing go.mod:
        module declares its path as: github.com/tree-sitter/tree-sitter-sql_bigquery
                but was required as: github.com/takegue/tree-sitter-sql-bigquery/bindings/go

So, I changed go.mod module from github.com/tree-sitter/tree-sitter-sql_bigquery to github.com/takegue/tree-sitter-sql-bigquery/bindings/go
