Add Elvish shell integration

[Yappaholic]

Elvish is a scripting language and interactive shell for Linux, BSD, MacOS and Windows. I decided to add elvish integration because found that it is somewhat similar to fish shell and it would be useful for elvish users to be able to use --use-on-cd feature of fnm.

try {{
  {version_file_exists_condition}
}} catch e {{
}} else {{
  fnm use --silent-if-unchanged
}}

Reason for this strange type of checking in src/shell/elvish.rs is that there is no way in elvish to view the exit code of the last command, so the best IMO way to do this is by catching error if test exits with 1 code.

set after-chdir = [{{|dir| {autoload_hook} }}]

Also, elvish has after-dir hook, which automatically runs the autoload_hook on directory change.

I tested it on Linux x86_64, hopefully it will work on Windows and MacOS too.
