chore: Avoid built-in tree-sitter languages in default. (#1135)
With a `tree-sitter-languages` feature to enable it (Default not
enable).

Changed this for reduce the application size (From 52 MB to 22MB), Ref
#1132

Now default only includes `tree-sitter-json`, if you want more:

```toml
[dependencies]
gpui-component = { features = ["tree-sitter-languages"] }
```
