jsr add and deno add commands should be able to install packages globally with -g or --global CLI flag

[arafathusayn]

Reproduction

$ deno add -g jsr
error: unexpected argument '-g' found

  tip: to pass '-g' as a value, use '-- -g'

Usage: deno add [OPTIONS] <packages>...

For more information, try '--help'.

$ npx jsr add -g jsr

I hope, the commands are pretty clear to show the intent. A -g or --global flag support will be nice to have.
