Instructions
------------

If you are submitting a new feature, please follow the following steps:

1.  Fill out the template in full.
This includes providing screenshots and a link to the original feature
      request. If there isn't an existing feature request, we strongly
      recommend opening a new feature request BEFORE opening your PR to
implement it, as this allows us to review whether we're likely to accept
      your feature in advance, and also allows us to discuss possible
      implementations for the feature. If there is no associated feature
      request, your PR may be delayed or rejected without warning.
      
      You can open a new feature request by following this link:
      https://github.com/EssentialsX/Essentials/issues/new/choose

2. If you are fixing a performance issue, please use the "Bug fix" PR
template
instead. The "bug fix" template is better suited to performance issues.

3.  Include a demonstration.
If you are adding commands, please provide screenshots and/or a video
demonstration of the feature. Similarly, if you are adding a new API,
      please include a link to example code that takes advantage of your
proposed API. This will aid us in reviewing PRs and speed up the process
      significantly.

### Details

**Proposed feature:**  
<!-- Type a description of your proposed feature below this line. -->
This PR implements /powertoollist, which lists out all of a user's set
powertools.

Since all of a user's powertools reside within `UserData`, I utilized
this Map to query through all of a user's powertools.

**Environments tested:**    

<!-- Type the OS you have used below. -->
OS: MacOS Apple chip

<!-- Type the JDK version (from java -version) you have used below. -->
Java version: 22.0.2

<!--
Put an "x" inside the boxes for the server software you have tested this
bug fix on. If this feature does not apply to a server, strike through
the server software using ~~strikethrough~~. If you have tested on other
    environments, add a new line with relevant details.
