[info] Modernize via search api (#1376)

## Summary

The `devbox info` command is quite old and outdated. 

1. It returns results inconsistent with the `devbox search` results. It
also doesn't print much useful information except a poorly formatted
package-name and version.
2. Some users have asked in the past for understanding what a particular
package in the search results is for.

This PR leverages the search service's API to get the package
information, and also prints a summary of the package.

## How was it tested?

BEFORE:
```
> devbox info go
go-1.20.2

> devbox info [email protected]
Ensuring nixpkgs registry is downloaded.
Downloaded 'github:NixOS/nixpkgs/1c6eb4876f71e8903ae9f73e6adf45fdbebc0292' to '/nix/store/y3kz7n62fwvp331na0k17xdw4dyaa66d-source' (hash 'sha256-hI7+s1UVDsJNqNn9UGV6xTBGqMC4dqOyVpeDf+su7JU=').
Ensuring nixpkgs registry is downloaded: Success
go-1.19.2

> devbox info php
php-with-extensions-8.1.17

php NOTES:
PHP is compiled with default extensions. If you would like to use non-default extensions you can add them with devbox add php81Extensions.{extension} . For example, for the memcache extension you can do `devbox add php81Extensions.memcached`.

Error: open /Users/savil/code/jetpack/devbox/.devbox/virtenv/php/process-compose.yaml: no such file or directory
```

AFTER:

```
> devbox info go
go 1.20.6
The Go Programming language

> devbox info [email protected]
go 1.19.2
The Go Programming language

> devbox info php
php 8.2.8
An HTML-embedded scripting language

php NOTES:
PHP is compiled with default extensions. If you would like to use non-default extensions you can add them with devbox add php81Extensions.{extension} . For example, for the memcache extension you can do `devbox add php81Extensions.memcached`.

Error: open /Users/savil/code/jetpack/devbox/.devbox/virtenv/php/process-compose.yaml: no such file or directory
```

NOTE: the error with `devbox info php` still needs fixing...
