Clarify url base command (#7670)

Browse Source 
I noticed that the help for the `url` command was confusing (it wasn't
clear that `url` is just a base command that does nothing itself) and
the input type was also wrong. Fixed.

Before:
```bash
〉help url
Apply url function.

Search terms: network, parse

Usage:
  > url 

Subcommands:
  url parse - Parses a url

Flags:
  -h, --help - Display the help message for this command

Signatures:
  <string> | url -> <string>
```

After:
```bash
〉help url
Various commands for working with URLs

You must use one of the following subcommands. Using this command as-is will only produce this help message.

Search terms: network, parse

Usage:
  > url 

Subcommands:
  url parse - Parses a url

Flags:
  -h, --help - Display the help message for this command

Signatures:
  <nothing> | url -> <string>
  ```
