feat: use asdf to determine elixir version

Browse source 
In order to speed up version checking for the elixir segment, this change makes
it so that we first ask asdf for the elixir version, which is much faster.

If asdf is not installed or configured, the previous behavior of running
`elixir --version` will be used.

This also makes a minor fix to the elixir documentation, replacing 'flutter' with 'elixir'.
