### To Reproduce

Run the command after installing the plugin:

`asdf list all php`

### Describe the Bug

Plugin php's list-all callback script failed with output:
awk: line 1: regular expression compile failed (bad interval expression)
({})

### Expected Behaviour

To be able to list all of PHP versions so I can start my download and installation

Start by running `asdf list all php` in the reported Linux and Bash environment, then inspect the plugin's list-all callback script that produces the awk regular-expression error. Done means the command completes without the bad interval expression and lists available PHP versions for installation.
