Use less generic globs for JSONC to avoid overmatching (#45162)

Otherwise, all *.json files under `zed` directory will be matched as
JSONC, e.g `zed/crates/vim/test_data/test_a.json` which is not right.
On top, `globset` considers that `zed/crates/vim/test_data/test_a.json`
matches `**/zed/*.json` glob (!).
