fix(json): remove jsonc parser from Treesitter (#1700)

* fix(pack.json): removes jsonc from ensure_installed options

Jsonc was removed from treesitter-nvim and is [not supported anymore](nvim-treesitter/nvim-treesitter#1997 (comment)). Trying to install it results on an error:

```
:TSInstallSync jsonc
Downloading tree-sitter-jsonc...
Creating temporary directory
Extracting tree-sitter-jsonc...

gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now

Error during tarball extraction.
Failed to execute the following command:
{
  cmd = "tar",
  err = "Error during tarball extraction.",
  info = "Extracting tree-sitter-jsonc...",
  opts = {
    args = { "-xvzf", "tree-sitter-jsonc.tar.gz", "-C", "tree-sitter-jsonc-tmp" },
    cwd = "/home/guel/.local/share/nvim"
  }
}
Press ENTER or type command to continue
```
